VGS-100W-24

The VGS-100W-24 is a high-performance enclosed AC/DC power supply manufactured by CUI Inc. Designed for demanding industrial environments, this unit delivers a stable 24 Vdc output capable of sourcing up to 4.5 A continuously. With a maximum output power of 108 W, it supports a broad range of control systems and instrumentation loads.

Electrical performance is optimized with a wide universal input voltage range accepting 85 to 305 Vac AC or 120 to 431 Vdc DC across 47 to 63 Hz frequencies. The converter achieves a typical efficiency of 89.5% at 230 Vac input, minimizing thermal waste. Input-to-output isolation is rated at a minimum of 4000 Vac, ensuring robust safety compliance for sensitive equipment. Additional electrical protections include over-voltage clamping at 38.4 Vdc, auto-recovery over-current protection between 110% and 160%, and continuous hiccup-mode short-circuit protection.

Thermal management allows reliable operation within an extended temperature range of -30°C to 70°C, with derating applied above 50°C. The switching frequency operates at 65 kHz, contributing to a ripple and noise specification of 150 mV peak-to-peak under standard measurement conditions. Line and load regulation are tightly controlled at ±0.5%, maintaining output stability during input fluctuations and varying load demands.

Mechanically, the VGS-100W-24 utilizes a rugged enclosed chassis mount design measuring 129.0 mm in length, 97.0 mm in width, and 30.0 mm in height. An integrated trim pot provides ±10% output voltage adjustability. This form factor and specification set make it suitable for panel integration in automation, telecommunications, and medical devices requiring isolated DC power.
