The PPS series laboratory power supply serves as a potential-free DC voltage source for operating low-voltage consumers. The adjustable output can be accessed from the front up to a maximum of 5 A and from the back up to the full rated current (1 - 18 V/DC / 0 - 20 A). Connection is made at the front via 4 mm safety sockets and at the back via high-current screw terminal sockets. Voltage and current settings are made continuously using digital rotary controls with coarse and fine adjustments to enable quick and precise value setting. The values are displayed on a clear screen. The current limit for constant current operation can be preset without a short-circuit bridge. Three freely programmable memory slots can be assigned different fixed voltages and current limits. Additionally, the power supply can be controlled via the included software and USB connection for operating cyclical processes through a PC. Up to 20 programmable voltage and current sets with varying durations can be programmed for operation. The cyclical processes can be repeated up to 999 times. Special feature: programmable.
