HPA Programmable AC Power Source
The HPA series is a variable frequency AC power source that reproduces the voltage and frequency used in any country on a single bench. It delivers...
View SpecificationsStart From The Markets You Ship To
List the destination voltages and frequencies first. A source covering 0 to 300 VAC and 40 Hz to 499.9 Hz spans the common 50 Hz and 60 Hz markets and the 400 Hz avionics and marine case in one unit.
HPA Programmable AC Power Source
Waveform And Isolation Decide Repeatability
A pure and stable sine wave with galvanic isolation keeps utility distortion out of the measurement. Without it, the same unit under test measures differently on a Monday morning and a Friday afternoon.
Overload Rating Is About Inrush
Transformers and motors draw many times their rated current on switch on. A sustained 300 percent overload capability lets the source start them instead of tripping.
Protection Keeps A Failed Unit Under Test Cheap
Look for an electronic circuit and instant trip breaker with alarms for overload, over temperature, instant cut off and short circuit, and a clear reset procedure.
Metering You Can Read From The Bench
An LED display of output voltage, frequency, ampere, wattage and power factor removes a separate meter from the setup and makes the test log faster to fill in.
Confirm The Load Type
Check the source is rated for resistive, capacitive, inductive and non linear loads before you assume it will drive a switch mode power supply under test.
FAQ
Questions Buyers Ask
Do I need 400 Hz capability?
Only if you supply avionics, marine or military equipment. The same unit covers it, so specifying it early costs nothing later.
What input supply does the source need?
Input frequency can be 50 Hz, 60 Hz or 400 Hz.
