INTRODUCTION
The MMA series is a regulated, versatile, modular HV power supply used in a wide variety of applications including photomultiplier tube, laser power supply, RF power supply, ionization chamber, proportional counter tube, Geiger-Miller (GM) counter tube, electrophoresis, lens, mass spectrometer, detector, microchannel plate, scintillator, electron and ion beams, Electrostatic printing, high voltage bias, medical chemical industry, scientific experiments, industrial applications. The MMA series is a printed circuit board mounted high-voltage power supply with a small size and ultra-high stability. The MMA series has protection features such as over-current protection and short-circuit protection. they are an excellent choice when you require a highiy stable output, which can be controlled using either an external control voltage or external variable resistor. With a diverse range of models up to 2KV/1W, you will find something for nearly every requirement.
