Manufacturing and Designing Multi-Channel Power Supply to Test Aerospace Components, Sensors, Actuators, Ripple Durability, and Watt Meters

Amp-Line Corp. offers multi-channel power supplies. These power supplies are compact and are usually available in 2 channels or more. Instead of using several individual power supplies or amplifiers, multiple channels can be built into a single unit to meet the requirements of the application.

Our model AL-90-CR-L/A-9 is a 9-channel AC constant current power amplifier designed to test multiple aerospace components. Instead of purchasing 9 independent constant current power amplifiers, we designed a single 9-channel power amplifier that can output 10 watts per channel, with an output current of 0 - 1 A rms. at 10 V rms. compliance voltage and a frequency range of 200 Hz - 2 kHz.

For applications like testing sensors and actuators, we built model AL-120-CR-L/A-6, a 6-channel constant current power amplifier with multiple output current ranges. Each of the 6 channels can provide 2 output current ranges: 0 - 1 A rms. at 20 V rms. compliance voltage, and 0 - 4 A rms. at 5 V rms. compliance voltage. The output frequency range is 50 Hz - 2 kHz.

Multi-channel power supplies are not limited to constant current applications. Model AL-600-CV/S-7K-2 is a 2-channel AC constant voltage power source used to provide a 7 kHz AC signal to test the ripple durability of Toyota motors. This unit provides 300 watts continuous per channel, with 0 - 28 V rms. adjustable output voltage at the primary of the internal output transformer and 0 - 1.4 V rms. output voltage at the secondary of the internal output transformer. The frequency is fixed at 7 kHz.

In addition to multiple channels of the same type of power source or amplifier, we also manufacture hybrid power supplies that combine different types of outputs in one unit. Model AL-45-CR10A-CV260-RS232-2 is a 2-channel AC constant current and constant voltage power source, with one CC channel and one CV channel, and an RS232 interface. This unit was designed to test watt meters.

The output specifications for model AL-45-CR10A-CV260-RS232-2 are as follows:

Constant Current Mode Channel:
  • Output Current: 0 - 10 A rms.
  • Output Power: 15 watts max.
Constant Voltage Mode Channel:
  • Output Voltage: 0 - 260 V rms.
  • Output Power: 30 watts max.
As you can see, Amp-Line Corp. designs and manufactures multi-channel and hybrid units to better meet our clients’ needs. Depending on the application, we can combine multiple channels, different output ranges, or different types of power sources into a single unit.
