The RUSSCO Charger provides on-board charging of both flooded and sealed lead acid battery systems of 84 to 144 volts. The battery charger operates off standard 120 VAC. It provides a constant current to 80% charge, then reduced current to finish, and the SO model has the added shut off.
Convenient features include a pre-wired, 25 foot, #12 AWG AC power cord, prewired DC cord terminating in a 50 A Anderson connector and easy front panel adjustments for AC current, DC battery voltage taper and charger shut off at finish. A built-in 3 1/2 digit LCD DVM monitors AC Line Current, AC Line Voltage, DC Battery Current and DC Battery Voltage.
Safety features include ground fault interrupt protection, power-on indicator, AC line circuit breaker protection, DC fused output, electronically regulated AC line current limit at15 A AC, 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 equipment heating and lowering radio/TV interference.
Battery packs of 84 V to 12O V may be charged without a boost transformer. The charger is expandable to 144 V systems with an optional boost transformer.
An optional battery temperature sensor is available for an additional $40 which reduces the charger output if the battery temperature rises to a preset level.
Will ship UPS within US.

I beta tested the first 120 Vac model with my 120 VDC battery pack of 20 Optima sealed batteries. I found it very useful but suggested to Russ that for sealed batteries we need another pot to adjust the maximum shut off (SO) voltage. This is the model I have permanently mounted in the MGA along with a 220 Vac Zapi charger.
I use one of each, the 240 Vac Zivan which is isolated and the 120 Vac Russco on one side of the same 240 V circuit. I can get 32.5 A for the 120 VDC battery pack when 240 is available with a neutral. I have not tried it yet on 208 Vac. If I am current limited on the ac supply I can use either the Zivan or the Russco charger depending on the voltage available.
