ProCharge Ultra Plus- The Ultimate Battery Charger

32 VOLT, 20 AMP ADVANCED BATTERY CHARGER, SECOND GENERATION UPGRADE


New for 2022, our second generation updated line of Marine Grade, Power Factor Corrected Battery Chargers set a new standard of what you should expect from your battery charger when it comes to features, performance & price. Years of experience in the battery charging industry has provided us the insight to include everything we could possibly think of and combine it all into the ProCharge Ultra Plus line of feature rich, high performance marine grade battery chargers. This exceptionally efficient power factor corrected battery charger runs on any Global AC Power source between 80-270 volts, requires less input power, produces less heat and noise waste, while still retaining a remarkably small, lightweight footprint. Did we mention Eleven pre-programmed battery charging curves as well as 4 user customizable battery profile for Lead Acid or Lithium Batteries? Adjust absorption time and custom set charge, float voltages and ) DegC temp trip protection. Optional BMS signal & optinal positive signal feed to bring all the custom settings you need to your next project. The digital dispaly allows easy checking of real time voltage or current output on the face of the charger or use the optinonal multi-lingual remote control that can be either surface, recess, or flush mounted over 30 feet away from the battery charger.

The ProCharge Ultra has been recently Updated to a 2nd Generation. The ProCharge Ultra Plus has a few new features:

Page 9, 10 and 11 of the new PCU manual cover the new optional Auxiliary Control Cable and the new Adjustable Absorption Time Window and the Easy Access tabs for the bottom cover.

The Auxiliary control cable allows for 2 things:

BMS shut down, if the red cable is grounded to 0V the PCU stops charging – in operation the red cable sits at 12V. So, if someone has a BMS that sends a ground signal then this can be used. If the BMS sends a positive signal a relay is required between the red and black wire

(i.e. short pos and neg to turn PCU off)

The purple cable is not really for battery charging at all – it is for a signal to turn something on. Notably a PSR, for example, you would feed the purple cable to the PSR to turn the PSR on to allow for the PCU to charge up all the batteries within a system using all of the pre-existing cable / fuses to save having to re-run new cabling. Also, if people don’t wish for a BB to turn on, they can feed that purple cable in to BMS port on the BB Ultra (for example).

Other new PCU differences:

Custom lithium charging profiles, as lithium batteries are newish to the market, there is all sorts of opinions about charge voltages and absorption time lengths. Here you can just customise absorption, float and absorption time length.

Additionally, We’ve put tabs on the side of the red end cap. Historically, if people lost the screws that hold the end caps down, the end cap could fall off. Now, with the tabs, it shall be held on with tabs + screws.

What size of charger do I need?
Most companies recommend a battery charger to be about 10% of the amp hour capacity of the batteries requiring to be charged. Sizing a charger to 15% to 20% of the amp hour capacity is the sweet spot and will result in a faster charge time. However, if you have a generator set onboard and you wish to charge your batteries faster - ie, to save fuel, then depending on your budget, you can easily add more charging current or multiple chargers to reach 30% rule of thumb of the charger size matching the battery amp hours to reduce your generator running hours and achieve even faster charge times.

 

Larger requirements?
After your final calculations are made if you require a larger charger please note because they are digital chargers, the Sterling Power ProCharge Ultras can be added together. Simply install a second or third charger as if the first charger wasn’t there. They will work great together in parallel.  For larger requirements simply add as many units together as needed to meet your largest of amperage requirements. Additionally, sometimes multiple smaller units can offer some advantages over 1 larger unit: They tend to be lower cost, have a built in redundancy, (in event of one failing) and enables you to switch one off in the event of low shore power facility.  

 

 

Power Factor Correction
Power efficiency of the Pro Charge Ultra is significantly higher than its predecessors. The PCU runs at >90% efficiency and the power factor is rated at 0.99PFC this is in contrast to a non-PFC charger which runs at approximately 65% efficiency. Thus, the same power output with a reduced power input saving you money on kilowatt-hours. Other major benefits of PFC allows the unit to run off a dirty / modified / quasi sine wave from a generator (example). The other advantage of this technique is less heat is liberated during operation, therefore reduced use of fan and stress on the electronic components.

 

Synchronized Rectification
Modern, synchronized rectification with MOSFET technology makes the Pro Charge Ultra Series 9% more effective. Less heat liberated and increased efficiency are also features of this latest technology.  Boasting an elegant yet functional design. The Pro Charge Ultra housing was designed by a renowned American product designer. In the foreground stands optimal function and clean lines. The housing is made of plastic and the back is made of well protected metal plate with the latest corrosion coatings, all other metal fixtures and fittings are stainless steel or nonferrous.

 


11 preset charging algorithms & 1 custom sett
ing
The Pro Charge Ultra has 11 different charging characteristics for corresponding types of batteries: Gel, AGM, sealed, open, calcium, LiFePO4. If these should not suffice there is 1 customizable setting which the user can set themselves - simply enter the absorption time, charge and float voltages then press enter and the settings save.

 

Automatic Desulphation / Equalization
Every 7-10 days the Pro Charge Ultra undertakes a desulphation / equalization and anti-stratification program which keeps your batteries young and rejuvenated.  

 


Performance monitoring LED bar
A bar of LEDs display the percentage to which the Pro Charge Ultra battery charger is operating at. This is easily and quickly recognized at a glance and can be easily analyzed.

 

32 LED display
32 LEDs built into the front panel provides all the necessary information about the charger including: charging status, battery chemistry select, temperature and voltage warnings along with many others.


Redundant high voltage protection device
In the event of a failure of the main processor this unit provides another safety system to shut off the device. Doubling the levels of security.

 

Variable Fan speed
The internal temperature of the device ultimately runs the speed of the fan. This guarantees a minimum possible noise. So called ‘thermostatically controlled force draft cooling’


Programmable Power Reduction

The Pro Charge Ultra can also charge with variable performance levels. The following performance levels available are: 100%, 75%, 50% & 25%. This can be controlled via the front panel or via programming the remote control. Power reduction is often used if the power supply to the charger is inadequate (e.g. small generator) but still enables competent levels of battery charging. Another benefit of power reduction is to reduce fan noise, as less heat is liberated.

 

Three Isolated Charge Outputs 
The Pro Charge Ultra has 3 isolated charging outputs. 3
batteries or battery banks can charge without the batteries themselves being interconnected, e.g. Starter, domestic and generator starter battery. Thru battery resistance the charger can adjust on the fly and send full current capacity of the charger down one output, or it can spread the current output across all banks if the batteries are empty it senses resistance and makes output decisions.

 


Small, lightweight and powerful

The Pro Charge Ultra series is characterized by its very compact, low
weight and small footprint structure. 

 

Voltage + Current LED display
2 LED matrix displays. The left matrix displays the voltage output from the charger and the right matrix displays the current leaving the charger.

 

Splash protection
For vertical mounting, the unit has drip water protection. The protection class is IP22. It meets the requirements of the ABYC drip test.

 

Global Application
The Pro Charge Ultra will operate with AC voltages ranging from 80V-270VAC (40- 70Hz) and DC voltages of 130-320VDC.

 

 

New features on this product surpassing that of standard battery chargers include:

1) 11 pre-programmed battery curves including: Open/Sealed lead acid, AGM, Gel, LiFePO4.
2) 1 custom set, can be set from charger, unlike our competitors there is no need for a computer to do this operation, all can be done from the front panel.
3) 2 x digital meters for current and voltage measurement and a 32 LED information display.
4) 1 x power meter to show what reserve power left in the unit.
5) PFC, active, up to 0.99 PF, ensuring efficient power conversion, up to almost 90% as opposed to about 60% for older, non-PFC technology.
6) % power reduction to allow unit to work with restricted power available (available on local control or remote control panel).
7) De-sulphation auto cycle built in to software.
8) New, low activity, standby mode to increase battery life.
