Teltonika WEHO — DIN Rail Power Supply 12V 20W 1.67A for Industrial Networking Devices

The PR3PDNP0 is a compact 20 W / 12 VDC industrial DIN rail power supply designed to power Teltonika industrial routers and gateways directly from distribution panels and automation cabinets. It is deployed in industrial installations, telecommunications infrastructures, and remote monitoring systems where the power supply must integrate into the electrical panel alongside other DIN rail equipment within limited space, with high demands on output stability and continuous protection.

The wide input voltage range of 85–264 VAC / 47–63 Hz ensures global compatibility with any electrical supply without additional adjustments or adapters, simplifying standardization on a single product reference across international projects. An efficiency of 80% and fine output voltage regulation of ±1% guarantee stable and predictable power delivery for sensitive devices, including Teltonika industrial routers with 9–30 VDC input requirements. The 1.5 kV input-to-output isolation protects connected equipment from mains disturbances and provides the galvanic separation required in industrial installations with high electromagnetic interference.

Overcurrent protection at 105–160% with automatic recovery and overvoltage protection at 120–140% with an off/on cycle prevent damage to connected equipment during electrical fault scenarios without requiring manual intervention to restart after an overload event. The compact 22.5 × 90 × 100 mm footprint and 190 g weight allow integration into high-density electrical panels, occupying a single 22.5 mm DIN slot. The operating temperature range of -10 °C to +50 °C covers the typical conditions found in industrial automation cabinets and technical rooms.

Natively compatible with Teltonika industrial routers including the RUT901, RUT906, TRB256, and other portfolio devices with 9–30 VDC input, providing a complete and standardized power solution for DIN rail deployments. Recommended for system integrators and OT teams equipping automation panels, telecommunications infrastructures, and remote monitoring installations where the DIN rail power supply, industrial router, and other active equipment must coexist in a compact cabinet powered from a single AC mains source.
