The HESC104 is a 60W DC-DC converter that includes a flash based microcontroller and 4 amp charger for advanced power management and smart battery charging. Combined with a Tri-M standard battery pack or super cap module, the HESC104 can be used as an Uninterruptible Power Source (UPS) for a PC/104 system. 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 (5000W) that clamp the input voltage to safe levels, while maintaining normal power supply operation. The +/-5V DC and +/-12V DC outputs are controlled by a constant off-time current-mode architecture regulator that provides excellent line and load transient response.
The HESC104 provides up to four stages of battery charging and can charge SLA, NiCd, and NiMh batteries and level two and 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. In addition to smart charging and power management the HESC104 can monitor up to 16 different temperatures using digital I²C digital temp sensors. The HESC104 is available as RoHS, is PC/104 compliant and -40°C to +85°C is standard.

Frequently asked questions
Q. How do I get SCU to run under WIN2K or WINXP?
A. Windows "NT" based OS require an I/O driver such as Porttalk.
Q. How do I get SCU to run under Linux?
A. There are a number of approaches such as executing SCU.exe under the WINE enviroment.
Q. Is there an equivalent GUI for Linux as SCU for Windows?
A: Tri-M offers a GUI for Linux.

A. The term HESC refers to any of the HESC products. When reference to a specific model is required, the specific model name (HESC-SER, HESC-SERD or HESC104) is used. From the command function point of view, there are few differences between the HESC-SER, HESC-SERD and the HESC104 even though they have different Host interfaces (the SMBus is usually thought of as a battery interface, but it may also interface with a Host CPU or a microcontroller)
A. The HESC104 can be commanded off via a hardware interface, or through a software command as follows.
1. Software Interface:
2. Hardware Interface:
A: If for some reason, (like an incorrect profile setting) the main outputs don't come on, wiring +5V into the HESC +5V outputs will enable communication with the HESC again (Main input power still needs to be applied as usual).
The profile settings can then be "fixed" and saved and when the HESC is re-powered, the changes will take effect.
Note: The procedure for uploading the firmware and profile is listed at the back of the HESC-UPS firmware manual.
A. The HESC can charge Lithium Ion batteries if:
A: None of the Tri-M products are "certified" for space, however they are frequently used in that environment. A special version of the HESC (removal of the one and only electrolytic capacitor) allows the HESC to be used in ultra low-pressure environments such as space. Removal of this one capacitor increases the minimum input voltage to 12 volts but the maximum 40 volts is still valid.
A. The SD input is used by an external maintained contact switch (such as an ignition switch) to signal the HESC to initiate a shutdown or startup of the HESC104 main outputs (not including the battery charger).
A. An example of the calculation required follows:
The BAT104-NiMh, when fully charged, can provide up to 22.68 Watt-Hr (2.7Ahr x 8.4V) of power backup. The system draws 1.5A @ 28 volts (not including battery charging) and therefore is a load of 42 watts. A 20 percent derating is required because of the 2.5C current draw from the battery. From this it can be derived that the BAT104-NiMh could sustain the system for a total of:
0.8 *((22.68 Watt-Hr)/(42 Watts)) = 0.432Hr = 25.92 minutes.
A. The battery charge level information is available through the through the PC/104 bus (HESC104), RS232 serial port (HESC-SER), and or the SMBus/I2C bus (HESC104 and HESC-SER) through the HESC-UPS firmware command "BattRemCapCmd(0x0F)”. The HESC104 does not have an analog output pin to indicate the battery level.
A. The EEprom ChTempSelect(0x90) register defines which temperature sensor to use. If this register is set to zero, the thermistor will be used, otherwise a digital sensor is used. In addition, the address and command of the digital sensor must be correctly set. Please refer to section Section 7: EEprom Setpoints and Configuration Variables of the HESC-UPS manual.
