MG Electronics Power Supplies and Transformers

MG Electronics is the power and cabling end of a CCTV or access job: plug-in transformers, multi camera power supplies, AC to DC converters, battery packs, and the adapters, cable and accessories that go with them. Browse the full MG Electronics catalog below.

Plug In Transformers

The plug-in transformers are the volume line here and they are listed by output. 24VAC is listed at 20VA, 40VA and 50VA, 16.5VAC at 40VA and 50VA, and 12VAC at 20VA and 40VA, all Class II. DC versions cover 12VDC at 500MA, 1.5A and 2A and 24VDC at 1000MA and 2000MA, with a wide 100-240V input at 50/60Hz.

The PTC versions are listed with an auto resetting fuse and a 3rd ground prong. Fused models are listed with an LED so a dead supply is visible without a meter, and most carry UL, cUL and FCC listing with two screw terminal outputs.

A dual voltage plug-in transformer with four taps powers two units from one outlet, and open frame signaling transformers are listed for long wire runs where a plug-in pack will not hold voltage.

Multi Camera Power Supplies

A camera power supply replaces a row of plug packs with one box and one circuit. Units are listed at 9 channel and 16 channel with 12VDC at 800mA or 1200mA per output, fully regulated, with individually PTC auto reset protected outputs so one shorted camera does not take the others down.

Fused 9 camera versions are listed to UL 2044 with 5.2A total, a 16 camera unit splits 8 outputs at 12VDC and 8 at 24VAC for a mixed install, and a 24VAC nine output supply carries integral surge protection. A weather resistant aluminum supply in a NEMA 4X box is listed for IP cameras outdoors, and a 9 channel power distribution board with battery charger is listed selectable at 12 or 24 VDC.

Converters and Batteries

AC to DC converters are listed converting 24VAC to 12VDC at 800MA and 1500MA, fully regulated, which is how a 12V camera runs off an existing 24V supply without a second circuit.

A 12VDC 4500mAh lithium-ion rechargeable battery pack is listed with its charger and a built-in on and off switch, UL listed, for a temporary install or a position with no permanent power.

Sounders, Cable and Accessories

Sounders cover a panel mounted piezo audio buzzer rated 90db with 5 inch lead wires, and a surface mounted piezo mini siren in a high impact black ABS casing with a high frequency warble at 110db.

Cable and adapters cover RG59U cable assemblies with BNC connectors on each end, BNC plug to BNC and BNC male to female adapters, 4 way 2.1mm splitters, and combined power and video cable in 20 AWG at 50, 100 and 150 feet with BNC to RCA adapters included. Flat panel wall mount brackets for 13 to 24 inch monitors on VESA 75 and 100 and a range of 70 volt and 8 ohm speakers round out the line.
