Protection, DIN Rail Installation and DC OK Indicator
The NDR-480 Series is designed for industrial DIN rail power supply applications that require stable DC output, cabinet installation, and basic status indication. Instead of remote control or remote sense functions, this series focuses on reliable power conversion, protection functions, DIN rail mounting, and simple front-panel output status indication.
With built-in protection functions, free air convection cooling, and TS-35 DIN rail compatibility, the NDR-480 Series is suitable for industrial control systems, factory automation equipment, control cabinets, and electro-mechanical apparatus.
Protection Functions
The NDR-480 Series includes short circuit, overload, over voltage, and over temperature protection. These protection functions help improve system reliability when the power supply is used in industrial control panels and automation equipment.
For overload protection, the datasheet specifies 105–130% rated output power. The unit uses constant current limiting and shuts down after 3 seconds, with re-power-on required for recovery. For over voltage protection, the output shuts down and re-power-on is required to recover. For over temperature protection, the output shuts down and recovers automatically after the temperature goes down.
DIN Rail Installation
The NDR-480 Series can be installed on standard DIN rail TS-35/7.5 or TS-35/15. Its 85.5mm width helps save cabinet space while providing 480W rated output power for 24VDC or 48VDC systems.
For permanent full-power loading, the datasheet recommends installation clearances of 40mm on the top, 20mm on the bottom, and 5mm on the left and right sides. If the adjacent device is a heat source, 15mm side clearance is recommended.
Terminal Assignment
The NDR-480 Series uses separate input and output terminal blocks. According to the mechanical specification, TB1 is used for FG, AC/L or DC+, and AC/N or DC- input connections. TB2 is used for DC output connections, with terminals assigned to +V and -V output.
Correct terminal wiring, cabinet ventilation, and derating review are important before installation, especially when the power supply is used near full load or in higher-temperature environments.
DC OK Indicator
The front panel of the NDR-480 Series includes a DC OK indicator and output voltage adjustment access. The DC OK indicator provides a simple visual reference for output status during installation, inspection, and maintenance.
