Product Overview
Burleigh PZ-70 Variable High Voltage DC Power Supply - Used
The Burleigh PZ-70 is a variable high-voltage DC power supply designed for laboratory and industrial applications. This unit is rated for 0–500 V with a 50 kΩ load, or 0–1000 V with a 100 kΩ load.
Burleigh instruments have a reputation for precision and durability in demanding test and research environments. This PZ-70 shows external signs of use but remains in clean condition. It has been powered on and verified for HV output. Marked as “modified,” though inspection suggests only two rear-panel plugs were added and not wired to the internal circuit.
Product Condition
Used. Unit powers on and produces high-voltage output as rated. Full functional testing was not performed. Marked as “modified,” but additional connectors on the rear panel are not wired internally. Cosmetic wear consistent with age and use.
Product Overview
The Burleigh PZ-70 delivers adjustable high-voltage DC output for applications requiring stable and controllable power in the 500 V to 1000 V range. Built for reliability, it has long been used in lab, research, and technical environments where high-voltage precision is required.
