CALRAD DV-1212A AC-DC Switching Power Supply Unit

CALRAD 45-752-DV-1212A is a compact AC-to-DC switching power adaptor that supplies a regulated 12 VDC at up to 1.2 A from standard mains. Built by CALRAD, this model is identified as 45-752-DV-1212A and is listed by distributors as a discontinued CALRAD supply; it is designed as a general-purpose adaptor for small electronics that require a stable 12-volt supply. The unit accepts 117 VAC at 50/60 Hz input and delivers 12 VDC output, making it suitable for devices with modest power requirements in locations where a plug-in 12-volt supply is preferred. Weighing approximately 1.17 pounds, the adaptor is a compact option for installations where space is limited. As a 12 VDC, 1.2 A supply, it is appropriate for peripherals and devices with modest current demands, such as CCTV accessories, sensors, or control modules that operate on a 12-volt rail. The 45-752-DV-1212A model aligns with CALRAD's broader line of power adaptors and CCTV power supplies, though this specific variant is no longer manufactured, so availability depends on remaining stock from distributors or resellers. When replacing or matching this unit, verify the connector type and polarity for your equipment to ensure compatibility with the 12 VDC output and current rating.
