Overview
The VT-42SPD-DC65 is designed to protect 40–65 VDC power systems against transient overvoltages caused by lightning-induced surges or equipment switching.
With a nominal voltage of 48 VDC, it is suitable for DC power cabinets in telecommunications, data centers, and industrial control systems. Its wall-mounted design, integrated circuit breaker, and status indicators support convenient monitoring, operation, and maintenance.
Feature
-
Type 2 DC surge protection: Helps protect sensitive electronic equipment against transient overvoltages.
-
160 kA maximum discharge current: Specified for an 8/20 µs test waveform.
-
Response time below 25 ns: As stated in the product documentation.
-
Five MOV status LEDs: Monitor MOV1–MOV5. An illuminated LED indicates normal operation; an unlit LED indicates a fault or disconnection.
-
Integrated 63 A circuit breaker: Provides power switching for the surge protection device during operation and maintenance.
-
Replaceable modules: Support convenient servicing.
-
IP54 enclosure: Compact construction for wall mounting.
