Dormakaba ES100 Power Supply for 1 DE Device or 2 LFSC / LFSF Trims

The ES100 powers one DE exit device, or two LFSC/LFSF electrified trims. It has two zones, each rated 24 VDC at .65 amp continuous with a 6 amp surge for 0.5 seconds. If you have a second DE device on another opening, you need a second supply.

The enclosure measures 8 inches high by 8 inches wide by 4 inches deep, with a hinged cover and knock-outs for conduit. It is a NEMA 1 type box, which is indoor use only. Exterior walls, parking structures, or anywhere it can get wet needs a different rated enclosure.

No. The ES100 tops out at .65 amp continuous per zone across two zones, which covers a single DE device or a pair of LFSC/LFSF trims. A multi-door panel needs real amperage and multiple protected outputs: the Altronix AL1024ULACMCB gives 24VDC at 10A across 8 PTC outputs, and the RCI DKPS-2A gives 8 outputs at 12/24VDC 2A. Pick by total load, not door count.

Three carry battery backup in the product itself: the Adams Rite PS-1 is a regulated 1 amp 12/24 volts DC supply with battery backup, the Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup, and the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup. If the delayed egress opening has to hold its function through a power loss, that requirement drives the selection rather than the ES100's zone output.

Motorized latch retraction has its own supply: the BEST RPSMLR2 Series is a power supply for motorized latch retraction exit devices. The ES100 is specified for one DE exit device or two LFSC/LFSF trims, with 24 VDC at .65 amp continuous per zone and a 6 amp surge for 0.5 seconds. MLR devices draw a sustained motor current rather than a half-second inrush, so match the supply to the device type rather than to the voltage alone.

The BEST PS161-6 is the nearest match on the electrical side. It is a power supply for delayed egress exit devices with a 120V input, 12/24V output and 6A capacity, which lines up with the ES100's 120 volt input, 24 VDC output and 6 amp surge rating. The difference to check before you order is device pairing: the ES100 is built to run one DE exit device or two LFSC/LFSF trims, so if the openings are Dormakaba DE hardware, the ES100 is the intended supply and the PS161-6 is the generic delayed egress alternative.

Look at multi-output boards. The Altronix AL1024ULACMCB is a power supply and access power controller with eight PTC outputs delivering 24VDC at 10A from a 115VAC 60Hz input, and the RCI DKPS-2A gives eight outputs at 12/24VDC and 2A. The ES100 powers up to 2 devices - one DE device or two LFSC/LFSF trims - so a job with six or eight electrified openings on one riser is the case for a distributed-output board rather than additional ES100 units.

Output protection on the ES100 is a 3 amp push-to-reset circuit breaker. A short or an overload trips it, and you reset it by hand at the board rather than replacing a fuse. That matters on a maintenance call: no spare parts to carry, but somebody has to physically get to the box.

Straight power supply. The ES100 converts 120 volt line power to 24 VDC on two zones with a 3 amp resettable breaker, and that is the whole job. It carries no relay logic, timing, or input sequencing. If you need delay timing or a control module in the same box, that is a different animal, like the BEST ELR150 power supply control module or the Detex 10-800 universal logic controller.

You need a 120 volt AC branch circuit to the box and low voltage runs out to the device. The enclosure comes with knock-outs and a hinged cover, so conduit lands at the box, but the conduit, fittings, and the wire itself are on you. Plan a location an electrician can reach for the line side and a maintenance tech can reach for the reset breaker.

Yes. The Command Access PS1 is a 24VDC linear power supply with a 1 amp output, and the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection. Both are sized for a single small 24VDC load. The ES100 is built around 24 VDC at .65 amp continuous per zone with a 6 amp surge for 0.5 seconds, which is the inrush headroom a motorized or delayed egress device needs and a plain strike does not.

No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish - it carries current across the gap between frame and door leaf. The ES100 is the source of that current: 120 volt input, 24 VDC output in an 8 inch high by 8 inch wide by 4 inch deep NEMA 1 enclosure with a hinged cover and knock-outs. An electrified opening typically needs both, one to make the power and one to get it into the door.

The ROFU 9126T is a plug in mini power supply rated 12 VDC at 1.5A with a time delay, and the ROFU 9102-12D UL/9102-24D takes a 10/120VAC 60Hz input. A plug-in unit needs a receptacle near the opening and sits exposed, while the ES100 comes in an 8 inch by 8 inch by 4 inch NEMA 1 type indoor enclosure with a hinged cover and knock-outs for conduit, and includes a 3 amp push to reset circuit breaker on the output. Where the spec calls for hard-wired 120 volt supply in a wall-mounted can, the enclosure is the deciding difference.

The ES100 is the power source - 120 volt input, 24 VDC output per zone with a 3 amp push to reset circuit breaker on the output. If the job also needs sequencing or logic, the Detex 10-800 Series is a universal logic controller that carries its own 120VAC/24VDC power supply, and the BEST ELR150 Series is a power supply control module for electronic access control. Those combine the two roles in one enclosure, which matters when panel space in the closet is tight.

For an intercom entry kit, the Aiphone AC-PS1250 is the supply built for that system - 12V DC at 5A, UL Listed, for AC Series access control kits. The ES100 is scoped to Dormakaba DE exit devices and LFSC/LFSF trims at 24 VDC, so it belongs on the electrified exit hardware rather than on the intercom head end.

The ES100 delivers .65 amp continuous per zone at 24 VDC. If the load list runs past that, the SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection, the Securitron AQS1210 is a switching supply at 12 VDC and 10 amp, and the Altronix AL1024ULACMCB provides 24VDC at 10A. Add up the continuous holding current of every device on the circuit, not the surge, when you size against these.

The Securitron BPSS is a boxed solar power supply, which is the option when getting 120 volt branch circuit to the opening is the obstacle - a gate, a detached structure, a remote perimeter door. The ES100 requires a 120 volt input, so where that feed does not exist the choice is between pulling the circuit and using a supply that does not need it.

For a single low-draw trim, a 1 amp class supply covers it and takes less wall space. The Command Access PS1 is a 24VDC linear supply with 1 amp output, and the SDC 620 is a 1 amp regulated and filtered supply with dual voltage selection. The ES100 is worth the box when you want its two independent 24 VDC zones for a pair of LFSC/LFSF trims.

The Command Access CAT Field Tester is a 12-24VDC portable power supply compatible with DeWalt, Makita and Milwaukee batteries, meant for bench-checking a device before or during install. The ES100 is a fixed 120 volt input unit in an 8 inch by 8 inch by 4 inch NEMA 1 indoor enclosure and is not a portable tool, so most installers carry the field tester alongside the permanent supply rather than in place of it.
