Applications
The NDR-90-24 is designed for industrial automation and control panel applications including PLC power supply, sensor and actuator power distribution, HMI and touchscreen display power, relay and contactor control circuits, industrial communication equipment, building automation systems, process control instrumentation, and machine tool control panels. The DIN rail mount design enables quick installation and replacement in standard electrical enclosures.
Installation Notes
The NDR-90-24 clips directly onto a standard 35mm DIN rail (EN 60715). Connect AC input (L, N, FG) and DC output (+V, -V) using the screw terminal blocks. The DC OK relay contact can be wired to a monitoring system for power-fail alarm functionality. The fanless design requires no special ventilation considerations, but ensure adequate spacing between adjacent DIN rail devices for heat dissipation. The output voltage can be adjusted using the built-in ADJ potentiometer. For redundant power configurations, multiple NDR units can be paralleled using external ORing diodes.
