Product Overview
The RD40-1700-C4 sits at the top of the Diamond line: a Red Diamond hybrid where transformer isolation and IGBT high-frequency conversion combine to serve 80V batteries across every chemistry on three-phase power at 20–36 kW (up to 500 A). A single programmable unit replaces separate conventional, opportunity, and fast chargers — streamlining the battery room without limiting capability.
- Output voltage: 80V (auto-identifies 24 / 36 / 48 / 80 V)
- Power class: 20–36 kW (up to 500 A)
- Chemistry support: Flooded lead-acid, GEL, AGM, Lithium
- Modes: Conventional, opportunity, fast-charge, equalization, formation, de-sulphation, regeneration
- Cabinet: TL or TP — TL: 19″L × 20.9″W × 36.6″H / TP: 22″L × 28.0″W × 47.6″H
- Phase: Three-phase (3Ø), 480 VAC
- Charging System: Hybrid Charging System
Configured for 480 VAC three-phase input — the practical minimum for this power class. Backed by a 5-year parts / 10-year power transformer warranty. Contact your representative to configure the RD40-1700-C4 for your fleet's voltage, chemistry, and shift schedule.
