DC Auxiliary Power Input
Operating Range: 40 to 60Vdc within rated limits
AC Input
Voltage Range: 110/115/120Vac: 89 to 138Vac
208/220/230/240Vac: 176 to 276Vac
Over Voltage Threshold:
276 / 138Vac
Under Voltage Threshold:
176 / 89Vac
Back-feed Protection:
Comply with safety requirement
Redundant Power Supply Design:
Startup by priority source or alternative
NOTE: the over/under voltage must be set by controller, if there is no additional setting, STS will adopt the widest range
to set over/under voltage in order to guarantee its performance, for 110/115/120Vac system, the range is 89Vac
(under voltage point) to 138Vac (over voltage point), for 208/220/230/240Vac system, the range is 176Vac (under
voltage point) to 276Vac (over voltage point). But once the STS is set by user, it will keep the setting whether a
controller exists or not, until such time that the STS is set by user again or next time the source connected to STS
is changed from 120V (110/115/120) to 230V (208/220/230/240) or 230V (208/220/230/240) to 120V
(110/115/120).
