VMS-100C-24

The VMS-100C-24 is a 100W open-frame AC/DC converter manufactured by CUI Inc. Designed for chassis mounting, this power supply module accepts a wide input voltage range of 85 to 264 Vac or up to 370 Vdc, operating across a frequency range of 47 to 63 Hz. It delivers a nominal 24Vdc output capable of sourcing up to 4.16A continuously.

Electrical performance includes a typical efficiency rating of 95%, with line regulation maintained within ±0.5% and load regulation within ±1%. The unit features a minimum hold-up time of 15 ms, an adjustable output via built-in trimpot (±5%), and over-voltage protection that triggers at a minimum of 32 Vdc. Input characteristics show a maximum inrush current of 40A at 115 Vac and 75A at 230 Vac during cold start conditions.

Thermal operation is rated from -40°C to 85°C with derating applied at higher temperatures. The module incorporates 4 kV of voltage isolation between input and output circuits. Its physical dimensions measure 76.2 mm in length, 50.8 mm in width, and 35.1 mm in height, making it suitable for integration into industrial control panels, telecommunications equipment, and automated machinery where reliable off-board power conversion is required.
