Centaur Charger

Quality without compromise
Aluminium epoxy powder coated cases with drip shield and stainless steel fixings withstand the rigors of anadverse environment: heat, humidity and salt air.
Circuit boards are protected with an acrylic coating for maximum corrosion resistance.
Temperature sensors ensure that power components will always operate within specified limits, if needed byautomatic reduction of output current under extreme environmental conditions.
Universal 90-265V AC input voltage range and also suitable for DC supply (AC-DC and DC-DC operation)
All models will operate without any adjustment needed over a 90 to 265 Volt input voltage range, whether
50 Hz or 60 Hz.
The chargers also accept a 90-400 V DC supply.
Three outputs that each can supply the full output current
Three isolated outputs to simultaneously charge 3 battery banks
Each output is capable to supply the full rated current.
CentaurBattery Charger 24 30

Three-stage charging, with temperature compensation
The Centaur charges at bulk rate until the output has reduced to 70% of the rated Amps, at which a 4 hour timer
begins. After the timed period the charger switches to float rate.
An internal temperature sensor is used to compensate the charge voltage with – 2 mV/ºC (– 1 mV/ºF) per cell.
A DIP switch is available to select the optimum charge/float voltages for Flooded Lead-acid, Gel or AGM
batteries.

BMV-700 Battery Monitor

Battery Alarm

The BMV-700 Battery Monitor features anadvanced microprocessor control system
combined with high resolution measuringsystems for battery voltage andcharge/discharge current. Besides this, thesoftware includes complex calculation
algorithms, like Peukert’s formula, to exactly
determine the state of charge of the battery.
The BMV-700 selectively displays battery
voltage, current, consumed Ah or time to go.

An excessively high or low
battery voltage is indicated byan audible and visual alarm.

Fasten the separate mounting
plate (A) to the wall where youwant to place the battery charger,and simply hook up the Centaur.
Secure the bottom of the backside(B) to the wall.
