EPS-D Series Rolling Door UPS, 600 W-6 kW

A rolling door that cannot open is a blocked loading bay, a locked shopfront or a trapped vehicle. The EPS-D series is an emergency power supply built specifically around that problem: a pure sine wave inverter, built-in batteries and microprocessor control in a compact steel enclosure, with enough short-term overload capacity to start a motor rather than just keep a router alive.

Where it fits

Use it on roller shutters and garage doors, tubular and translation-door motors, high-speed fast doors, retractable expansion gates, industrial sliding gates and flap-gate motors — the loads a general IT UPS is not designed to start. Single-phase 6D/7D/12D/20D wall-mount units suit individual doors and small premises; the 30D/50D three-phase cabinets serve door banks in factories, logistics centres and multi-bay car parks. Boost and buck AVR plus a wide input window (160-270 Vac single phase, 330-415 Vac three phase) keep it working on the unstable supplies common at these sites.

Sizing and selection

Start with the motor's rated power and starting current, not the door width. The catalogue maps the family to door classes from 0.6 T to 3 T and lists two output-power rows per model — continuous rated output (600-5000 W) and short-term motor-starting output (800-6000 W). Size against the starting figure with margin, and treat the peak figure as a surge rating, not a continuous one. Then decide how many full open/close cycles the site needs during an outage; the built-in battery strings run from 7 Ah x 2 on the 6D to 12 Ah x 8 on the 50D, and we size the pack against that cycle count.

Output voltage and phase are factory builds. Confirm 220 Vac single phase or 380 Vac three phase against the site supply before ordering — a 110 V version or a different plug is an OEM configuration, not a switch on the back of the unit. MOQ, lead time and private-label options are confirmed at quotation.

This model is the first purpose-built series in the Special-Purpose UPS sub-category — one of the seven sub-categories under UPS Power Supply, reserved for UPS systems engineered for one specific operating scenario. Further scenario-specific series are added there as they are released. For general backup of PCs and office equipment, see the Offline UPS range; for transformer-isolated heavy industry systems, see Industrial UPS. The full UPS Power Supply category lists all seven sub-categories.
