Functions 8-1 Adjustable output voltage Output voltage can be set by applying 0 to 10V between the terminal s for output voltage control , the Vcont (4Pin) and SGND (3Pin). Avoid setting out of the adjustable output voltage range or it may cause trouble. 8-2 Monitoring output voltage and output current Output current monitoring terminal, the Imon i (7pin) and output voltage monitoring terminal, the Vmoni (8pin) generate 0 - 10V proportionate to output of the converter. An internal impedance of each terminal for monitoring is 1kohm . The internal impedance of each terminal for monitoring is 1kΩ. Do not allow monitoring current to exceed 2mA PGND, SGND, casing and HV GND are connected inside.

High Accuracy, Low Noise Mid -to-High Voltage DC -DC Converter 10,000V, 15,000V NHV Series DC-DC Converter BHV20170526_B01 8-3 Reference voltage Reference voltage output terminal, the Vref (5pin) generates reference voltage of 10V. This terminal is used when controlling output voltage by a variable resistor ( 5kΩ min.). L eave this terminal open when output voltage is adjusted by external voltage. Do not allow reference current to exceed 2mA. 8-4 Overcurrent protection If output current becomes 105% or more of the rated current value, over current protection (OCP) functions to lower the output voltage. Si nce this over current protection is an auto restart type, output will resume upon release of the overcurrent state. 8-5 ON/OFF control Output voltage can be turned ON/OFF by open ing or short -circuiting between the ON/OFF (6Pin) and the SGND (3Pin) without turning on/off the input voltage. In the case of not using the ON/OFF control, short-circuit these two terminals. Use an open collector type. ・Open between 6 and 3 (6V max.): Output Off ・Short between 6 and 3 (0 – 0.3V, 2mA max.): Output On 8-6 Thermal shutdown This function works upon the abnormal rise of the ambient temperature or the temperature inside this power supply to stop the oscillation of the converter and the supply of out put power. If the t hermal shutdown functioned, shut down the input and wait some time for the temperature to come down sufficiently (after eliminating the cause) before reclosing. NHV SGND
