SUMIT VL-EPMs-PS1 DC/DC converter

The VL-EPMs-PS1 is a plug-in 50 W switching DC/DC converter and power supply module designed to power an embedded system stack.

The supply is suitable for powering systems in defence, aerospace, medical devices, robotics and factory automation.

The in-stack supply provides clean, reliable, noise-free power to the heart of larger systems. It eliminates the problems associated with distributing clean, properly regulated power within automated systems, especially those that include motors and other sources of electrical noise.

Voltage sag, intermittent operation and unexplained system resets are eliminated by having a dedicated in-stack power source for the control system.

The converter is designed to support OEM applications where high reliability and long-term availability are required. From application design-in to 5+ guaranteed years of production life, the device is fully RoHS compliant. Customisation is available, even in low OEM quantities.

The VL supply provides up to 50 W of continuous power. The unit operates over a +9 to +40 VDC input range to produce standard output voltages of +5 and ±12.

Output is delivered through the stackable SUMIT and/or ISA connectors to power compatible boards while auxiliary terminal blocks provide output power for sensors, transducers and other ancillary circuitry.

The module is designed to operate over an extended temperature range (50 W from -40 to +60°C; 25 W at +85°C) and is certified to MIL-STD-202G specifications for shock and vibration. Input protection clamps voltages to safe levels while a 10 A fuse protects the card from overcurrent.

Regulation and transient suppression reduce supply ripple and protect the computer circuitry from power source hazards. Input protection guards against input polarity reversal of up to +40 VDC.
