Tridonic EMconverterLED PRO 202 MH/LiFePO4 50V DALI-2 Emergency LED Driver – 89800627

The Tridonic EMconverterLED PRO 202 MH/LiFePO4 50V is a self-contained emergency lighting converter with a DALI-2 interface and automatic testing. It is designed for integration into non-maintained LED emergency luminaires.

During a mains failure, the converter switches the designated LED module to battery-powered emergency operation. It supports one or more LED modules with a combined forward voltage between 10 and 54 V and provides a typical constant emergency output of 1.5 W.

The selectable duration link allows the unit to be configured for 1-, 2- or 3-hour emergency operation. The converter is supplied with the link in the 3-hour position and must be configured before connecting the battery and mains supply.

Its DALI-2 interface enables central testing, configuration and monitoring. The automatic self-test system monitors the battery and LED load, conducts a weekly five-second function test and performs an annual full-duration test.

Three-pole switching technology provides two-pole LED-module changeover and delayed power switching for the associated normal LED driver. The converter is compatible with most constant-current LED drivers, subject to the limits specified in the Tridonic datasheet.

The electronic charging system automatically detects approved NiMH or LiFePO4 battery technology. Integrated protection includes deep-discharge prevention, a short-circuit-proof battery connection, reverse-polarity protection and automatic shutdown when the connected LED load falls outside the permitted range.

The low-profile 179 × 30 × 21 mm enclosure is intended for integration into a suitable luminaire. An optional strain-relief enclosure is available for approved independent installations.

AUTOMATIC TESTING AND MONITORING

The PRO converter provides automatic monitoring of:

• Connected battery condition


• Emergency LED condition


• Charging operation


• Function-test results


• Duration-test results


• Emergency system faults

A compatible two-colour status LED provides local indication:

• Green: System operating normally


• Red: Fault detected

Testing, monitoring and selected operating parameters can also be managed through a compatible DALI-2 emergency-lighting control system.

BATTERY COMPATIBILITY

The converter supports approved high-temperature NiMH and LiFePO4 batteries. Battery selection depends on the required emergency duration.

Examples include:

• Selected one-cell 1.5 Ah LiFePO4 batteries for 1-hour operation


• Tridonic 28002318 3.0 Ah LiFePO4 battery for approved 2- or 3-hour configurations


• Selected two-cell NiMH battery configurations

Always consult the current Tridonic battery-selection table before ordering. A matching connector does not by itself confirm electrical compatibility.

IMPORTANT COMPATIBILITY INFORMATION

This is the 50 V model and requires an LED load with a combined forward voltage of 10–54 V. Check the normal LED driver, LED module and battery against Tridonic’s current compatibility information before ordering.

The battery, status-indicator LED, test switch, cables, DALI controller and strain-relief enclosure are not included unless expressly stated by the seller.

Installation and commissioning must be completed by a suitably qualified person. The DALI control input is not SELV and must be wired in accordance with the requirements for low-voltage installations.
