Negative High-Voltage Power Supply HVP-3KV, 0 to -3000 V (CAT#: STEM-AL-5581-ZJF)

The HVP-3KV is a laboratory negative DC high-voltage power supply designed for applying negative bias to electrospinning collectors. It operates with a positive high-voltage source through a common ground arrangement. The negative collector potential can guide fibers toward the receiving assembly and support directional collection. A rotary potentiometer sets the output from zero to the rated negative voltage. Digital displays indicate voltage and current. Shutdown with automatic recovery provides output protection after a fault condition. Load, temperature, and time drift specifications define the regulated output behavior. The unit is intended for laboratory electrospinning systems that require a separate negative collector supply.
