The PSwitch-N4UM is a smart 4-channel power switch module designed for mobile DVRs, vehicle cameras, and telematics systems. It ensures stable power management, safe ignition control, and synchronised system start-up and shutdown for dependable in-vehicle performance.
Full Product Description
The PSwitch-N4UM is an intelligent power control unit engineered for professional vehicle surveillance and telematics installations. Acting as an interface between the vehicle ignition system and devices such as mobile DVRs, IP cameras, or telematics trackers, it provides automated power switching, over-current protection, and voltage stabilisation.
Built to enhance system reliability and installation efficiency, the PSwitch-N4UM allows up to four independent outputs, each controllable for precise power distribution. When the ignition is turned on, the unit activates the connected devices automatically and powers them down safely when the vehicle is switched off, preventing data loss and protecting hardware longevity.
With rugged automotive-grade components, the PSwitch-N4UM is suited to fleets, buses, lorries, taxis, and logistics vehicles where reliability and consistent performance are essential.
