Extron VNM 12 PSR (part number 70-762-01) — an external 12 VDC power supply with an extra redundant module, feeding up to 12 VN-Matrix codecs from a single 1U rack-mount enclosure.

Drawing 90 to 264 VAC at 47-400 Hz, VNM 12 PSR delivers 1300 watts of full power through three 350-watt modules onto a single 12 VDC rail, rated for 1050 watts of continuous output — one more module than the standard VNM 12 PS, giving the rack N+1 protection against a single module failure. The supply requires a minimum 3 A load with at least two Extron VN-Matrix codecs connected, and includes continuous short-circuit protection with auto recovery plus thermal protection that disables the DC output if the unit overheats.

Key Capabilities

• 1300W full power input delivers 1050W on a single 12 VDC rail
• Three 350W modules provide an extra module of redundancy over VNM 12 PS
• Powers up to 12 VN-Matrix codecs from one external supply
• Continuous short-circuit protection with auto recovery
• Front-panel fan cooling and integrated mounting brackets for 1U rack installation

Where It Is Used

VNM 12 PSR centralizes power for larger or mission-critical VN-Matrix codec racks in command centers and AV distribution rooms where a single power module failure must not take the rack offline.
