NEMIC LAMBDA HR-11-20 Regulated Switching Power Supply

Overview

NEMIC LAMBDA HR-11-20 is a single output enclosed switching power supply from the HR-11 series. NEMIC LAMBDA HR-11-20 converts AC mains input to stable 20VDC output for industrial control, test equipment and legacy machine auxiliary power loads. This NEMIC LAMBDA HR-11-20 is widely stocked as spare power supply unit for old factory automation assemblies.

Features

NEMIC LAMBDA HR-11-20 adopts metal enclosed perforated housing with built-in cooling ventilation. It supports wide AC input range, integrated overcurrent, overvoltage and thermal shutdown protection to safeguard downstream loads. HR-11-20 uses screw terminal connection for AC input and DC output, with output voltage trim potentiometer for minor adjustment. It is designed for rugged cabinet installation, compatible with continuous 24-hour operation. This series is discontinued by Nemic Lambda TDK and only available as maintenance replacement spare. The unit has stable load regulation and low ripple performance, suitable for powering legacy PLC boards, sensor circuits and instrument panels. It follows original safety and EMC specifications for industrial power supply.

Specifications

NEMIC LAMBDA HR-11-20 Switching Power Supply Brand: NEMIC LAMBDA TDK Lambda Model: HR-11-20 Series: HR-11 Type: enclosed single output switching power supply Output: 20VDC, 6A, 120W Input: 85~132VAC or 170~264VAC selectable, 47~440Hz Protection: overcurrent, overvoltage, thermal shutdown Adjustment: output trim potentiometer Connection: screw terminal block Housing: perforated metal enclosure Mounting: chassis mounting inside control cabinet Protection class: IP20 Ambient temperature: 0℃ ~ +50℃, derating at higher temperature Status: discontinued legacy spare

Principle

NEMIC LAMBDA HR-11-20 converts AC input voltage via high frequency switching topology. This Regulated Switching Power Supply maintains constant 20VDC output against input fluctuation and load variation. Internal protection circuit limits or shuts down output current when fault conditions occur to prevent load damage.

Applications

NEMIC LAMBDA HR-11-20 is deployed in legacy industrial machine control cabinets, test bench systems, old semiconductor equipment and factory instrument power loops. It supplies 20VDC power for control boards, sensors and small actuators. NEMIC LAMBDA HR-11-20 is stocked as spare power supply for legacy industrial control assemblies.
