Q: What are multi-phase programmable power sources?

A: A multi-phase programmable constant current mode power source and constant voltage mode power source are phase angle adjustable power sources. They are equipped with functions to adjust output amplitudes, output frequencies, output phase angles, output enabled/disabled, and open/closed loop control through PC via RS232 or GPIB (IEEE-488.2) interfaces.

Q: What are the applications of multi-phase programmable power sources?

A: They are especially favorable for applications that require accurate phase adjustments and for applications that require external feedback for further voltage and current regulations.

Q: How many output channels do they have?

A: The standard models have three output channels, but we can do two, three, four, five, and six channels.

Q: What is the output power range?

A: The output power range is 150 watts to 750 watts. Higher power rating models can be formed by multiple-unit setups.

Q: What is the output frequency range?

A: The output frequency range can be sections of 30 Hz to 20K Hz.

Q: What modes do they have?

A: They are either Constant Current Mode or Constant Voltage Mode, or both.

Q: What are the output current ranges?

A: The output current range depends on the output power rating and output voltages of the unit.

• Model with an output power of 150 watts and with max. output voltages of 25 V rms. per phase has an output current of 0 – 2 A rms. per phase.

•  Model with an output power of 450 watts and with max. output voltages of 25 V rms. per phase has an output current of 0 – 6 A rms. per phase. 

•  Model with an output power of 750 watts and with max. output voltages of 25 V rms. per phase has an output current of 0 - 10 A rms. per phase.

Q: What is the output voltage?

A: The standard output voltage range (without internal or external output transformers) is 0 – 25 V rms. Custom output transformers can be added to achieve other output voltage ranges.

Q: Are they customizable?

A: Yes. If internal output transformers are added to the unit(s), the output voltage, output current, and frequency range will change accordingly. Please contact our sales or technical support team with your special requirements.
