CUS600 M-12/EF | TDK-Lambda | 600W Medical Grade AC-DC Power Supply;‑12 = 12V output, /EF = metal enclosure + built-in rear fan version

I. Appearance and mechanical structure (/EF closed fan version)

Appearance: Metal all-enclosed casing, built-in exhaust fan at the end, integrated whole machine, different from bare board open rack CUS600 M-12 (no EF suffix) TDK Produc...

Dimensions: 157 x 85 x 42.5 mm (less than 1U height), weight about 790g TDK products...

Interface: one end is AC input terminal, the other end is DC high power output terminal; The side shell has reserved holes for the installation of the entire machine; The nameplate and parameter label are attached to the top surface of the casing.

Heat dissipation: built-in rear fan forcibly exhausts air; Typical fan noise is 42dB; The fanless convection mode can only output 400W, and the fan must be turned on to output 600W.

Comparison: CUS600M-12 (without EF) is a bare board open rack, which requires a complete design of the casing and air duct; /EF directly with shell + fan, integrated whole machine is more convenient TDK-Lambda...。

IV. Analysis of Strengths and Weaknesses

✅advantage

/EF closed fan version, ready to use, no need to design the fan shell yourself, shorten the overall development cycle

True medical grade 2MOPP isolation, while compatible with industrial ITE devices; Supports I/II class complete machines

B grade EMC built-in, the workload of system EMC rectification is greatly reduced

Standard configuration: 5V standby, remote control, remote voltage compensation, suitable for complex integrated systems

High conversion efficiency, low standby power consumption, suitable for devices that need to be idle.

Convection mode 400W, peak 600W, both silent and peak impact load

V. Typical application scenarios

Medical equipment: in vitro diagnostic analyzers, life science instruments, monitoring, clinical auxiliary equipment (BF class)

Industrial testing equipment, semiconductor testing equipment, laboratory instruments

Robots, industrial automation, special equipment requiring medical safety regulations

A complete system with 12V high power, low EMI, and standby power is needed.
