FR-20H 2KVA Outdoor Uninterruptible Power Supply

FR-H Series

The FR-H are online double conversion UPS designed to operate effectively in an outdoor environment.

The wide operating temperature makes the systems suitable for all but the most extreme of environments. The systems are protected against temperature, humidity, dust, mould and corrosion.

The double conversion technology and of course, sinewave inverter, ensure the systems provide the highest levels of power protection, to the load, and of course, due to the increased risk of damage by lightning, all inputs to the UPS are extra protected against surge currents.

The IP56 rated cabinet gives plenty of room for a large battery - typically 100Ah to protect against prolonged outages. The UPS also has the capability to shed load as the available battery power starts to decline. The large charger ensures that the system is recharged quickly when the mains power returns.

Available in 1, 2 and 3KVA modules, the FR-H series is your only sensible choice for outdoor UPS applications.

Can be supplied with or without environmental cabinet
