The DR-UPS40 provides an uninterrupted supply of 24V up to 40A using a 24V battery supply. Wired in parallel with a the DC BUS, this offers a simple and neat installation.
N.B. Supply time is dependent on load and capacity of battery bank.
The DR-UPS40 can operate at an ambient temperature between -20ºC and 70ºC with free air convection.
