Tridonic EMconverterLED BASIC 202A MH/LiFePO4 250V Emergency LED Driver – 89800709

The Tridonic EMconverterLED BASIC 202A MH/LiFePO4 250V is a self-contained emergency lighting converter designed for integration into LED luminaires. During a mains failure, it switches the designated LED module to battery-powered emergency operation.

The converter supports one or more LED modules with a combined forward voltage between 50 and 250 V. It provides a typical emergency output power of 2.3 W, while the constant-power output automatically adjusts the emergency LED current according to the connected LED load and approved battery configuration.

A duration link allows the installer to configure the unit for either 1-hour or 3-hour emergency operation. The converter is supplied with the link fitted in the 3-hour position; removing the link selects 1-hour operation. The duration must be configured before connecting the battery and mains supply.

Three-pole switching technology provides two-pole LED-module changeover together with delayed mains switching for the associated LED driver. The unit is compatible with most dimmable and non-dimmable constant-current LED drivers, subject to the electrical limits stated in the Tridonic datasheet.

Its electronic charging system automatically recognises approved NiMH or LiFePO4 battery technology. Integrated safeguards include deep-discharge protection, a short-circuit-proof battery connection, reverse-polarity protection and automatic output shutdown if the LED load falls outside the permitted operating range.

The slim 179 × 30 × 21 mm polycarbonate enclosure is designed for installation inside a suitable luminaire. An optional Tridonic strain-relief enclosure is available where the converter is to be used independently outside a luminaire.
