Current Regulation Unequalled in a Module of This Price Range. For example, the regulation from short circuit to rated voltage for the 15 kV, 1 mA model is ± 500 nanoamperes. Glassman's "Air Insulated" designs are completely serviceable; this module is not an epoxy block "throw away". AC Input: Eliminates the need, and expense of an auxiliary DC power source. Standard Accessories: Detachable 8' shielded output cable, and mating control connector. Constant Voltage/Current Operation - Standard Low Stored Energy: Less than 200 millijoules for most models. "Multi-Mode" operation permits maximum user flexibility. * Local Voltage or Current Control, user selectable. * Remote Voltage and/or Current Control via 0 ~ +10 Volt signal. * Remote Voltage and/or Current Control via potentiometers. Protection: Overload, short circuit, and arc protection is provided by automatic current regulation and by careful surge limiting design. External Interlock Terminals TTL Enable/Disable Warranty. Standard power supplies are warranted for three years; OEM and modified power supplies are warranted for one year. A formal warranty statement is available.
