Solid state full wave design using generously rated power semiconductors for maximum reliability and long life. Both AC lines fused for maximum semiconductor protection in case of short circuit.
Massive heat sink for cooler operation gives longer component life.
3 Amp full wave designed field supply. LED indicator lights to indicate if drive is in current limit and indicated SCR gate triggering. Control relay to prevent drive from restarting after interruption of AC power. Tachometer feedback circuitry standard. Designed for use with 50 or 60 Hertz AC power.
