GE DS200NATOG2A
Product Name: Voltage Feedback Scaling Board (NATO), G2 Group Variant
Product Introduction: This board is a precision voltage attenuation hub designed for LS2100 Static Starter and Mark V Speedtronic control systems. It attenuates high AC phase voltages and DC bus voltages from SCR bridges, converting 1200–6900 V inputs to scaled low-voltage signals for control system processing.
