The small UPS people actually keep
Small UPS units fail in one of two ways: the batteries die quietly after three years, or the unit is so bulky nobody finds room for it. The LT500–1500 attacks both — LiFePO4 cells that hold up for years without maintenance, and a body that fits a shelf, a cabinet plinth or behind a counter.
Straightforward to specify
230 V in and out, pure sine wave, three capacity classes. If the load is a router, a switch, a recorder and a POS terminal, one of the three classes fits — send us the device list and we will confirm which, free of charge.
Key features
- LiFePO4 batteries built in — no external battery box

- Compact and light — fits where space is tight
- Maintenance-free; day-to-day, just watch the alarm indicator
- 230 VAC input and output, matching the Hong Kong standard supply
- Suited to shops, network racks and small office equipment
