Series S75DC150
Output to 150A, 42 Vdc
DC Solid-State Relay
FEATURES/BENEFITS
• Latest generation MOSFET technology
• Ultra low on-state resistance
• Innovative isolated driver ensures fast power transistor turn on and off and thus low
power transient
• Ultra low output leakage current
• Low control current consumption
• Triggered control input to avoid linear control risks
• Low conducted and radiated disturbances
