Aptec AHV-1B High Voltage Bias Power Supply - Used

The Ortec Aptec AHV-1B is a NIM BIN high-voltage bias power supply designed for radiation detector systems. With selectable ranges up to 5KV, it was a key component in laboratories and research facilities requiring precise detector biasing.

This unit represents the era when semiconductor radiation detectors became standard in nuclear physics and applied research. Built for stability and reliability, the AHV-1B provided the steady voltage required for sensitive detection systems. Decades later, its design still shows the overbuilt quality of instrumentation engineered for demanding labs.

Product Condition

Used condition. Basic testing performed. The unit powered correctly to dial setting up to 4.9KV, but we did not achieve the rated 5KV output. The 0-2 kV was tested with the expected output.

Product Overview

Aptec is a recognized name in nuclear instrumentation. The AHV-1B served as a critical bias supply for solid-state semiconductor radiation detectors, ensuring consistent operation across a wide voltage range. Its dual-range selection allowed flexibility for both low-voltage and high-voltage applications within experimental setups.
