3. Organic Semiconductor Capacitors provide filtering that reduces ripple noises below 20mV The low noise design makes the HE HP2 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 HP2 has an opto isolated on off input SD allowing for remote control The HE HP2 has a PC 104 footprint with PC 104 mounting holes All generated voltages are provided to a connector block HE HP2 User Manual Rev A www diamondsystems com Page 4 01amono SYSTEMS FEATURES eDC to DC converter for embedded applications e Load Dump transient suppression on input power supply eOperates from 6VDC to 40VDC input ePC 104 size and mounting holes e100 watt power supply outputs e5V and 12V outputs eTemperature range 40 to 85C eOpto isolated input for remote operation Li bi E C HE HP2 User Manual Rev A www diamondsystems com Page 5 01amono SYSTEMS 1 2 SPECIFICATIONS Power Supply Specifications Model HERZ OOO 3 55 W x 3 75 L x 0 6 H Current rating includes current supplied to 12Vregulators Measured on the 5V output LED s disabled HE HP2 User Manual Rev A www diamondsystems com Page 6 01amono SYSTEMS CHAPTER2 CONFIGURATION AND INSTALLATION 2 1 Introduction This cha
