Helios SRHi Series DC UPS

The SRHi Series DC UPS is designed to provide DC power to lead-acid batteries for critical back-up applications. No-Break DC UPS systems maximise the integrity of standby battery installations, while optimising the life and availability of backup batteries. They are available with Serial and Ethernet Communications options.

The No-Break system is suitable for critical systems of 100 to 250 W (and above, using parallel operation); and applications requiring continuous online monitoring of battery and charger status.

The UPS has separate outputs for load and battery; battery detection — regular battery presence and battery circuit integrity checks; battery deep discharge protection; power loss and battery system alarms; no transition switching to back-up battery; rugged design and construction for long life and challenging environments; and maintenance and repair service.

Optional features include communication port (RS232 ASCII — SR485 — MODBUS RTU — SNMP, webpages); digital input/outputs — customisable 3 digital inputs and 1 digital output; battery condition test option auto test enabled on start-up; mounting, DIN rail, rack mount 19″ with V/I meter available, wall mount; N+1 redundancy; and boost charger.
