TTL “1”or OPEN – will turn on the power supply. (For normal operation leave the signal not connected.) TTL “0” – will turn off the power supply. SENSE The SENSE is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load’s terminals). The use of remote sense has a limit of voltage dropout between converter’s output and load terminals of 2 – 10% of voltage output. When not used connect +SENSE to +OUT and –SENSE to –OUT. SYN IN signal The SYN IN signal is used to allow the power supply frequency to sync with the system frequency. The system frequency should be 250Khz ±10Khz TTL level. When not connected the power supply will work at 250kHZ. SYN OUT signal The SYNC OUT signal is used to sync the system with the power supply freque ncy. PAR IN signal The PAR IN signal is used to connect the power supply in parallel to other power supplies and have them divide equally the power between one another. All the power supplies should connect PAR IN signals together except the master unit where the PAR OUT signal connects to all the PAR IN signals. PAR OUT signal The PAR OUT signal is used to connect the power supply in parallel to other power supplies and have them divide equally the power between one another. The master unit connects the PAR OUT signals to all PAR IN pins of the slave units. -SIGNAL IN RTN The –SIGNAL IN is referred to the input ground. This Pin is used as grounding for INHIBIT, SYN IN, SYN OUT signals. -SIGNAL OUT RTN The –OUT SIGNAL is referred to the output ground. This Pin is used as grounding for PAR IN, PAR OUT and V/CAL OUT signal. V/CAL OUT The OUT V/CAL signal is used to control and adjust the output power of the power supply within the given tolerances.
