The HPS3512 is a high power, high performance PC104 PSU that supplies +3.3V, +5V, and +12V outputs. The HPS3512 also includes a flash based microcontroller that supplies advanced power management, and an RS232 serial port. The HPS3512 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 HPS3512 is specifically designed for vehicular applications and has heavy-duty transient suppressors (up to 18000W) that clamp the input voltage to safe levels, while maintaining normal power supply operation.
The HPS3512 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 (OSC-CON) and Polymerized Organic Semiconductor capacitors (POSCAP) provide filtering that reduces ripple noises below 20mV. The low noise design makes the HPS3512 ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized. Constant frequency architecture controllers provide excellent line and load transient response on the +5VDC and +12VDC outputs.
The HPS3512 has advanced power supply management functions that allows timed on/off control of the HPS3512, notification of changes to main power and secondary power status. For example, the HPS3512 can be programmed to power off the outputs in 60 seconds, and then turn on again 12 hours later.
The HPS3512 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 HPS3512 does not include the PC/104 bus connectors. All generated voltages are provided to a removable header. A removable plug allows the HPS3512 to be easily installed. The RS232 serial port is provided on a 2x5 row pin header.
The HPS3512 can be configured to meet almost any power supply and battery powered need for embedded applications, whether that is a simple +5V application, or providing power for backlighted LCD panels.

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.
