Introduction

The HE104-DX is a 60 Watt PC/104 DC-DC rugged power supply. The HE104-DX is specifically designed for the rugged requirements of vehicular applications and has heavy-duty transient suppressors (3000W) on both main and secondary inputs) that clamp the input voltage to safe levels, while maintaining normal power supply operation.

The HE104-DX is a state-of-the-art Mosfet based design that provides outstanding line and load regulation with efficiencies up to 95 percent. Organic Semiconductor Capacitors provide filtering that reduces ripple noises below 20mV. The low noise design makes the HE104-DX ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized. The HE104-DX has a wide input range of 6 - 40V DC (>6:1). The +5V, +12V, -5V and -12V DC outputs are controlled by a constant frequency architecture regulator that provides excellent line and load transient response. The HE104-DX is also available in a low cost, +5V and +12V output only configuration, the HE104-DXL.

The HE104-DX is a compact design measuring 3.55" x 3.775" x 0.9" and has an operating temperature of -40° to +85°C. The HE104-DX is available from stock and is now RoHS compliant.

Note: HE104-DX now has an MOQ of 25 boards - for orders less than 25, the updated HE104 (same power, improved performance) is recommended
