These ARDs are designed to match latest types of VFDs which operate from three phase power supply. With 4 to 10 SMF batteries it can perform rescue operation of a big elevator with 10 to 30 H.P. motor.
- IGBT/MOSFET base HF PWM 3 phase balance inverter with individual voltage correction.
- Mains fail sensing (any one out of three phases)
- Mechanically interlocked contactors for safe transfer of power.
- Manual bypass switch.
- Low ripple CVCC charger for long battery life using buck converter.
- Less than 1 mAmp current in shutdown mode to avoid battery over discharge.
- Field programmable delays.
- DZ signal for shutdown.
- NO, NC contacts for blocking mains between ARD operation.
- Auto shutdown if DZ signal is not available.
- 24V DC output for announceator (Optional).
- Vertical cabinet for MRL type controller
- LCD/LED display for ease of programming and status.
- Short circuit protection.
- Battery reverse polarity connection protection.
- Heavy duty din-rail mounting connectors.
