Sterling Pro Charge Ultra Battery Charger

Winner of Sailing Today’s premium product award, the Sterling Pro Charge Ultra may well be the ultimate battery charger.

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.
9) Battery health program every 7-10 days .
10) Multiple speed fan control. This reduces unnecessary fan noise experienced by the customer, even though the new extreme efficiency reduces the need for fans. At high ambient temperatures (40-50 deg C), however, fans would still be required to ensure operation.
11) Primary (processor digitally controlled) and an emergency backup secondary (analogue controlled) high voltage trip.
12) 32 LED information panel to ensure maximum information transmitted to owner.
13) Internal scan and systems check to ensure product is okay.
14) Remote control option.
15) Small footprint and light weight.
16) Include battery temperature sensor to give temperature compensation and high temp trip.
17) As with all our marine chargers all metals used are non-ferrous or heavily protected, so no corrosion.
18) New synchronised rectification output as opposed to diode output, giving up to an extra 9% efficiency.
19) Conforms to ABYC drip test, is waterproof from water directly dropped on to the top of the unit (+/ – 17 deg) if installed correctly (vertically).
20) Thermostatically controlled force draft cooling.
21) The printed circuit boards are conformal coated for high humidity and salt air operations.
