HESC-SERD: 60W Smart Embedded Power Supply

Manufacturer: Tri-M Technologies

Description

Overview

60 Watt High Efficiency Serial Port Embedded Power Supply

The HESC-SERD is a high efficiency, high performance DC to DC 60 watt embedded power supply that supplies +5V, -5V, +12V & -12V outputs. The HESC-SERD also includes a flash based microcontroller that supplies advanced power management, smart battery charger and an RS232 serial port. The HESC-SERD is designed for low noise embedded computer systems, has a wide input range of 6-50V(>8:1) and is ideal for battery or unregulated input applications. The HESC-SERD is specifically designed for vehicular applications and has heavy-duty transient suppressors (9000W) that clamp the main input voltage to safe levels, while maintaining normal power supply operation.

The HESC-SERD 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 HESC-SERD 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 HESC-SERD provides up to four stages of battery charging and can charge Lead-Acid, NiCd, and NiMh batteries and is also SMBus level 3 compatible. Charge currents are up to 4A, and battery charging voltages from 9.5 to 35V.

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

The HESC-SERD size is 3.55 x 3.775 inches, which is the same size as the PC/104 standard, and has the same mounting holes pattern as the PC/104 standard. However, the HESC-SERD does not supply the PC/104 bus connectors. (For a fully compliant PC/104 embedded power supply, please see Tri-M's HESC104.) All generated voltages are provided to a removable pluggable header. The removable plug allows the HESC-SERD to be easily installed. The RS232 serial port is provided on a 2x5 row pin header.

The HESC-SERD 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 (un-interruptible power supply configuration).
