Automatic current regulation protects the power supply against all overload conditions, including arcs and short circuits. Fuses, surge-limiting resistors, and low energy components provide the ultimate protection. B Bi-polar operation. Two supplies, with same voltage rating and opposite polarity, may be operated singlely or as a bi-polar pair. CT Current trip.
Power supply trips off when the load current reaches the programmed level.
TTL TTL compatible high voltage enable.
