HVP0.5P vs HVP0.5N 500V Converter Selection | Pico
The Pico Electronics HVP0.5P and HVP0.5N are compact, regulated high-voltage DC-DC converters with programmable outputs and a maximum power rating of 5W.
The primary difference is output polarity:
HVP0.5P: programmable from 0 to +500V
HVP0.5N: programmable from 0 to -500V
Both models accept an 11–16VDC input and deliver up to 10mA at full rated output. Selecting the correct model depends on whether the load requires a positive or negative high-voltage rail.

Which Model Should You Choose?
Choose HVP0.5P for Positive High Voltage
The HVP0.5P generates a positive voltage relative to the common connection. It is the correct choice when the load requires an adjustable positive high-voltage bias or supply rail.
Typical uses include:
Positive high-voltage bias circuits
Industrial test and measurement equipment
Electrostatic control systems
High-voltage laboratory instruments
Sensor and detector circuits requiring positive bias
Choose HVP0.5N for Negative High Voltage
The HVP0.5N generates a negative voltage relative to common. Select it when the load must be driven below the system reference or ground potential.
Typical uses include:
Negative detector or sensor bias
Scientific instrumentation
High-voltage measurement systems
Electrostatic circuits requiring negative polarity
Industrial equipment using an adjustable negative rail
The HVP0.5P and HVP0.5N are not positive and negative outputs from one dual-output module. Each part provides only one high-voltage output polarity.
Frequently Asked Questions
What is the main difference between HVP0.5P and HVP0.5N?
The difference is output polarity. HVP0.5P provides an adjustable positive output up to +500V, while HVP0.5N provides an adjustable negative output down to -500V.
Are these isolated DC-DC converters?
No. The HVP Series is non-isolated. Input common, output common and the metal case are internally connected.
What is the maximum output current?
Both models provide up to 10mA at the full 500V output, corresponding to a maximum output power of 5W.
Can HVP0.5P and HVP0.5N be combined for ±500V?
They are separate single-output modules, not a matched dual-output supply. Any bipolar connection must account for their common and case connections and should be reviewed with Pico Electronics before implementation.
Can the standard models operate from -55°C to +85°C?
The standard operating range is -25°C to +70°C. Expanded-temperature versions may be available under different ordering numbers and must be confirmed before purchase.
