Technical Data

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 ballast during emergency lighting test.


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

Voltage Sensing Circuit

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

Deep Discharge Protection

All modules are fitted with deep discharge protection (DDP) as standard. The rectified output modules may lead to mercury migration.
