The HESC104+ is a high efficiency, high performance PCI104 DC-to-DC converter that supplies +3.3V, +5V, +12V & -12V outputs. The HESC104+ also includes a flash based microcontroller that supplies advanced power management, smart battery charger and the PCI104 bus (also known as the Plus connector on the PC/104+ format). The HESC104+ 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 HESC104+ is specifically designed for vehicular applications and has heavy-duty transient suppressors (9000W on both main and secondary inputs) that clamp the input voltage to safe levels, while maintaining normal power supply operation.

The HESC104+ is a state-of-the-art Mosfet based design that provides outstanding line and load regulation with efficiencies up to 90 percent. Organic Semiconductor capacitors provide filtering that reduces ripple noises below 20mV. The low noise design makes the HESC104+ 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 frequency architecture regulator that provides excellent line and load transient response.

The HESC104+ provides up to four stages of battery charging and can charge Lead-Acid, NiCd, and NiMh batteries and level two and level three SMBus compatible batteries. Charge currents are up to 4A, and battery charging voltages from 9.5 to 19.5V.

The HESC104+ has advanced power management functions that allows timed on/off control of the HESC104+, notification of changes to main power and changes in the battery status. For example, the HESC104+ can be programmed to power off the main outputs in 60 seconds and then turn them on again 12 hours later.

The HESC104+ can be configured to meet almost any power supply and battery charging need for embedded applications, whether that be a simple +5V application, or providing power for back lighted LCD panels, or a full UPS (uninterruptible power supply configuration).
