THX ES25W

Self-testing UPS System for 230Vac devices or lamps up to 25W

  • Automatic self-testing feature with audible and visual status

  • Emergency lighting kit for 230Vac lamps from 3 to 25 Watts

  • 100% emergency lighting for 1 or 3 hours

  • Maintained or non-maintained operation

The THX_ES25W provides emergency operation for one hour duration using 230V ES, LED lamp or 230Vac device up to 25W load. Lamps will deliver 100% light output in emergency mode. This level of light output means that the THX_ES25W becomes a perfect choice when high output emergency lighting is required to provide good visibility for emergency situations in an exterior or interior application when using a single ES lamp.

This emergency lighting control unit incorporates a self testing facility that exercises the batteries and establishes lamp condition on a regular basis. Automatic tests are conducted monthly with full functional tests every 6 months. The monthly tests, of two minutes duration, establish battery and lamp condition whilst the 6th month tests last 40 minutes to remove battery memory effects. System faults are reported via both audible and visual means.

A 12V battery provides the power to the unit for the emergency operation. A safety start circuit is provided that prevents emergency operation until mains is connected. This enables installation without disconnecting or depleting the batteries. A red pilot light indicates that the batteries are being charged. The unit is housed in an alu-zinc case, which includes a wiring connection diagram.

FEATURES:

  • Automatic tests reduce maintenance requirements.
  • Single unit construction for reduced wiring requirements.
  • Satisfies SABS 1464 Part 22.

The indicating lamp reports the status of the batteries and the lamp by flashing at different intervals. An audible alarm emits a beep every hour of five seconds duration if a system fault is detected.

The built-in computer establishes whether the lamp is faulty, the battery voltage is low (shorted cell), the battery voltage is too high (old batteries) and if the batteries have lost capacity due to ageing. The user can now be aware of any problems with the emergency lighting system before power failures and not during them. The periodic use of the batteries also prolongs their life.

The built-in computer also prohibits deep discharging of the batteries.

This type of inverter is now becoming mandatory in Europe because users’ needs some guarantee that the emergency lighting is always fully functional .

The inverter satisfies the requirements as defined in SABS 598-1 (Luminaires: General requirements and tests) and will satisfy SABS 1464 PART 22 (Safety of luminaires: Luminaires for emergency lighting).
