The RUSSCO Safety Electric Vehicle Battery Chargers provide low cost, small size, and light weight on-board charging of both flooded and sealed lead acid battery systems of 72 to 156 volts. The battery chargers operate off standard 120 VAC. The RUSSCO Model SC18-120/72-156 draws 1800 watts from a 20 amp service, and the Model SC30-120 DSO/72-156 draws 3000 watts from a 30 amp service.

The RUSSCO Chargers provide two stage charging with adjustable constant current to 80% charge, adjustable constant voltage, then minimum current to finish. An automatic shut off (SO) option, available in analog or digital versions, shuts off the charger when the battery is fully charged. The RUSSCO two stage Chargers are ideal for flooded batteries. The Model SC30-120 DSO has timed digital shut off standard.

A Three Stage (3S) Charger option provides adjustable constant current to 80% charge, adjustable constant voltage, then third stage adjustable constant current with timed digital shutoff. The RUSSCO Three Stage Chargers are recommended for sealed batteries.

Convenience features include external line cord and booster transformer connections, prewired DC cord terminating in a 50 A Anderson connector and easy front panel adjustments for AC current and DC battery voltage taper. A built-in ammeter monitors DC Battery Current.

Safety features include an on/off toggle circuit breaker with ground fault circuit interrupt protection, power-on indicator, AC line circuit breaker protection, DC fused output, electronically regulated AC line current limit, soft-start up, overtemp protection, and fan cooling. A high power factor with low crest factor lowers AC line peak current while increasing line current duty cycle, reducing AC line heating and lowering radio/TV interference.

Battery packs of 84 V to 120 V may be charged without a boost transformer. The chargers are expandable down to 72 V and up to 156 V systems with an optional boost transformer.

RUSSCO Safety Electric Vehicle Chargers are warranted for one year.
