Switch Mode Power Supply
Mackwell patented Switch Mode Power Supply provides total short circuit protection, regulated output and complies with all relevant standards.

Ballast Delay Relay
All versions are fitted with an additional relay to switch off the power to the HF ballast during emergency lighting test.

Voltage Sensing Circuit
The AC power supply is sensed so that switching occurs at between 60% and 85% of the nominal mains supply.

The LED indicator is illuminated when a charge is flowing to the cells. Flexible 1x0.6mm high temperature orange and pink leads connect the indicator to the module. The indicator requires a 8mm hole.

Deep Discharge Protection
The inverter module incorporates deep discharge protection (DDP), to prevent damage to the batteries caused by deep discharge and possible subsequent reverse cell polarity.
Technology Options
For applications where self-testing is not required or suitable, the non-AutoTest® option provides the same quality and performance expected of Mackwell products, without the AutoTest® feature.
Relevant Standards
  • EN 61347-1
  • EN 61347-2-3
  • EN 61347-2-7
  • EN 60598-2-22
  • BS 5266-1
  • EN 62034
  • EN 62386
  • ICEL 1004
Lamp performance can be affected by lead length. Lamp wires should be kept to a bminimum length. Do not insulation test this product. The rectified output of these modules may lead to mercury migration of the lamp. Reversing battery polarity will cause damage.
