TP69A 250W Battery charging L-bracket switched mode power supply

Overview

250W lead acid battery charger
Remote sensing is used for compensating a voltage drop at the output wiring
Double-ended feed-forward topology
Temperate compensated output voltage guaranties an optimal lifetime of the connected battery
Active soft-start circuit adequately limits the inrush current at both cold- and hot start conditions
Custom made

Application

Traffic information displays at motorways
System consists of up to 20 charger and battery combinations
The chargers are parallelly contected to a single power bus
The connection provides active current sharing and an uninterrupted supply of power
