Description
The FSU1000 incorporates an onboard adjustable flash rate of 10 to 100 FPM and a universal input voltage in one device. Its circuitry is encapsulated and is capable of controlling loads of up to 20A. The versatility of the FSU1000 makes it ideal for applications where various flash rates and operating voltages are required. Operation When input voltage is applied to terminal 2 and the load (lamp), the load energizes steadily. When input voltage is applied to terminal 3, the output flashes. Optional Low Current Switch (S1): This low current switch could be a limit switch or contact. While open, the operator sees the load (lamp) ON and operating. When the limit switch closes, the load (lamp) flashes to attract attention. Features & Benefits FEATURES BENEFITS Universal input voltage 24 to 240VAC Allows flexibility for a wide range of applications with one part Onboard adjustable flash rate Provides flexibility for user to select flash rate between 10 - 100 FPM T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity High output rating up to 20A, 200A inrush Allows direct operation of high current loads without a contactor Accessories P1015-13 (AWG 10/12), P1015-64 (AWG 14/16), P1015-14 (AWG 18/22) Female Quick Connect These 0.25 in.
