ENGLISH
Introduction
The RND 305-00018 is a 4 Stage switch mode charger with MCU controlled constant current pulse Bulk,
PWM (Pulse Width Modulation) Absorption and PWM Float / Maintenance charge. It is suitable for all types
of 24V all types wet, sealed lead (GEL, AGM) acid, Calcium-Calcium ba ery. It can recondition lightly
sulphated lead acid ba ery. Though it is primarily designed for indoor use, it has a splash proof sealed
Polycarbonate casing.
!Please read this manual carefully and follow the instructions!
Features
1. 4 Stage Charge with constant current pulse Bulk, PWM Absorption & Float.
A. Check & Qualifying ba ery to Desulphate Pulse Charging.
B. Constant current pulse Bulk charge
C. PWM Absorption charge
D. PWM Float / Maintenance charge.
2. Wet, sealed lead (GEL, AGM) acid, and Calcium-Calcium ba ery type selection.
3. Select and forget operation and can be connected to ba ery for months.
4. Auto recover to last selected Charge Mode on return from AC power blackout.
5. Electronic wrong ba ery connection, short circuit protections
6. Over temperature protection from decrease in output current to shut down.
7. The Microprocessor unit (MCU) controls charging and monitors ba ery state of charge with advanced
PWM charging which makes it faster and saver charge your ba ery without overcharging or
undercharging.
