Generator Controller Panel DSE501K (Model 501K1) A manual engine control module for direct front panel key switch operation. Designed to start and stop the engine, display fault conditions with LEDs, and perform automatic engine shutdown on fault to provide true first fault notification. Key benefits Simple, secure manual control using a front panel key switch for authorized operation. Clear fault visibility via LEDs for fast diagnosis and first fault identification. Automatic shutdown on detected engine faults to protect equipment and reduce downtime. Wide input ranges and relay capacities for broad compatibility with common generator systems. Durable ABS housing in black for panel mounting and regular operational environments. Main specifications Model: DSE501K, variant 501K1 DC power supply: 9 to 33 V continuous Alternator input: 15 to 305 V AC RMS Alternator input frequency: 50 to 60 Hz at rated engine speed Magnetic input range: 0.5 V to plus or minus 80 V Magnetic input frequency: 2300 to 6000 Hz Start relay output: 16 A at DC supply voltage Run relay output: 16 A at DC supply voltage Time alarm output: 1 A DC Operating temperature range: 30 to 70 degrees Celsius Material: ABS Color: Black concern chemical: None Typical applications Standby and backup generator panels for commercial or residential buildings where controlled manual start and clear fault indication are required. Rental and portable generator sets that need a compact, reliable manual control module with automatic shutdown on fault. Industrial, construction, or agricultural generator installations using alternators and magnetic pickups within the listed input ranges. Practical notes Use with alternators and magnetic pickups that meet the specified voltage and frequency ranges for reliable operation. LEDs provide first fault notification to assist troubleshooting and reduce time to restore service. Ensure DC supply remains within 9 to 33 V for continuous operation and respect relay current limits when wiring external loads.
