Model Definition

CUS: Series designation, dual-purpose enclosed power supply for medical and industrial applications1200: Rated power of 1200WM: Medical grade24: Rated DC output voltage of 24V

II. Core Functions

High-power Conversion from Mains AC to Stable 24V DC

It converts 85~265V alternating current into 24V direct current to supply the main power circuit of complete machines. Equipped with active PFC, it delivers low harmonic distortion and strong adaptability to power grids.

Safe Isolated Power Supply for Medical Devices

It features 4000Vac reinforced isolation between input and output, with leakage current less than 250μA. It meets insulation and leakage safety requirements for Type B/BF medical devices to prevent electric shock hazards.

Multi-channel Auxiliary Monitoring & Remote Control

Comes standard with a 5V/2A standby power rail, remote on/off, remote sense and power good (PG) signal. These functions facilitate system control and voltage compensation to eliminate voltage drop over long output cables.

Low Noise & High-efficiency Heat Dissipation

Built-in variable-speed temperature-controlled fan runs at low speed of only 30dBA under light load and 42dBA at full load. It achieves a maximum conversion efficiency of 95.5% with low heat generation, and its compact body saves cabinet space.

Comprehensive Protection Functions

Integrated OVP (Over Voltage Protection), OCP (Over Current Protection), short-circuit protection and thermal protection. The unit latches off automatically upon faults to protect downstream loads.
