The HM34S Series is a family of high performance high voltage DC to DC converters.
The converters' outputs feature protection against electric shock according to EN 61010-1:2010 / IEC 61010-1:2010-06 Edition 3.0 when connected to accessible parts. The short circuit output current is being limited to <2mA under normal condition and <15mA under single fault condition. The stored charge is <45µC.
Designed for detector supply applications these converters are equally suitable for other applications requiring ultra low ripple, lowest noise and high stability. They are encapsulated in a metal package providing 6-sided shielding. These compact converters are ideal for applications requiring small size, high performance, low cost and ease of use.
The devices are available for 5VDC or 12-15VDC input voltage. The output voltage is programmable via an analog voltage, such as the output from a DAC or by a potentiometer connected locally to the converter's reference voltage output (VREF). The output voltage is directly proportional to the programming voltage. It features excellent linearity.
The output can be enabled via the /ON input by means of a TTL level signal or just by an external contact (internal pull-up). A voltage monitor output is provided. Load regulation is excellent and the output voltage is independent from the input supply voltage. The output is not isolated. High voltage return is internally connected to ground (GND).
