556h-rp.jpg (9520 bytes)The ORTEC Models 556 and 556H High-Voltage Power Supplies provide the noise-free, well-regulated, very stable high voltage necessary for proper operation of photomultipliers, ionization chambers, semiconductor detectors, electron multipliers, and many other devices. The Model 556 is housed in a double-width NIM module (per DOE/ER-0457T). The Model 556H is a stand-alone instrument designed for bench-top operation. The low-noise output is continuously adjustable from ±10 to ±3000 V dc with 0 to 10 mA load current. Noise on the output is <10 mV peak-to-peak, thereby ensuring the highest performance in high-resolution, semiconductor or scintillation spectroscopy systems.

The front-panel digital meter allows visual monitoring of either the output voltage or the output current.

The output voltage can be controlled from ±10 to ±3000 V by application of an external input voltage of 0 to ±6.9 V dc. This feature is desirable for control applications and is standard on all units.

The input power for Models 556 and 556H is taken directly from the ac line, either 115 or 230 V ac, 47 to 63 Hz.

Overload and short-circuit protection networks permit operation into short circuits without damage to the instrument.
