PLCs, Power Supplies & Others

The Schneider DNP 105 converts AC mains into stable DC voltage. This power supply weighs only 0.8 kilograms for lightweight mounting. Its dimensions measure 125 mm in height and 115 mm in depth. The width stands at 45 mm for standard DIN rail installation.

Technical Specifications of DNP 105

The Schneider DNP 105 accepts an input range of 85 to 264 V AC. It delivers a nominal output of 24 V DC at 5 amps. The unit achieves up to 90% efficiency under full load. Consequently, it wastes minimal energy as heat during operation. This power supply includes built-in overload and short-circuit protection.

Below is a complete breakdown of key parameters:

Internal Components and Energy Storage

The Schneider DNP 105 contains a single internal PCB assembly. It uses high-grade electrolytic capacitors for energy smoothing. These capacitors store enough charge for a 20 ms hold-up time. Therefore, the unit bridges short power interruptions without output dropout. The power supply has no internal battery for maintenance-free operation.

Installation and System Integration

You can mount this power supply on a standard 35 mm DIN rail. It requires only 45 mm of horizontal panel space. The Schneider DNP 105 features LED indicators for power and fault status. For similar industrial power solutions, see the RMS-TSG-TZ-C static trip unit. That unit provides reliable protection for power distribution systems. However, the DNP 105 focuses specifically on DC power conversion.

Reliability and Protection Features

This power supply includes overvoltage protection at 28 V DC. It also features automatic current limiting during overload conditions. The Schneider tolerates input surges up to 300 V AC. Moreover, its metal casing provides excellent heat dissipation and shielding. These features make it ideal for factory automation and control panels.
