The DC SMARTstart is used to monitor and control power for secondary distribution and incorporates both manual and remote operation. DC SMARTstart units feature independent programmable power-on and off sequencing delays that manage the level of inrush current transients. The unit will control and monitor two sets of six independent 4-amp loads. Each output channel is rated to operate at 4 amps of DC continuous power and trip at 5.3 amps of nominal DC. Units feature an input voltage range of 38.5 to 72 V DC. The operating temperature rating is 0 - 45°C and the operating humidity rating is 0 - 95% (non-condensing).
