Introduction

The HE-HP is a high efficiency, high-performance DC to DC 100 watt power supply module that supplies +5V and +12V outputs. The HE-HP is designed for low noise embedded computer systems, has a wide input range of 6-40V(>6:1) and is ideal for battery or unregulated input applications. The HE-HP is specifically designed for vehicle power supply applications and has four heavy-duty transient suppressors (providing 6000W of protection) that clamp the input voltage to safe levels while maintaining normal power supply operation.

The HE-HP 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 HE-HP ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized. The +5VDC and +12VDC outputs are controlled by a constant off-time current-mode architecture regulator that provides excellent line and load transient response.

The HE-HP has an opto-isolated on/off input (SD), allowing for remote control.

The HE-HP has a PC/104 footprint with PC/104 mounting holes. All generated voltages are provided to a connector block.
