ProportionAir PS-400 Quick start guide

Brand: ProportionAir

Model: PS-400

Type: Quick start guide

ProportionAir PS-400 is a power supply designed for use with Proportion-Air's line of electronic pressure regulators. It provides DC power and signal conditioning, allowing for amplification, attenuation, and offset adjustment of DC voltage signals. The PS-400 can also invert the DC voltage signal and is safety fuse protected. With its versatile features, it's ideal for various applications requiring precise control and conditioning of DC voltage signals.

Power Supply

DESCRIPTION

The PS-400 power supply is designed for use

with Proportion-Air’s line of electronic pressure

regulators. In addition to being a DC power

supply, it has a signal conditioning circuit which

is designed to accept a DC voltage signal and

either amplify or attenuate it as well as offset it

for specific applications. The circuit is also ca-

pable of inverting the signal by repositioning

two jumpers.

Adjustments

Inverting/Non Inverting: For normal operation insure the jumpers are in the normal position. For a inverted signal output,

place the jumpers in the inverted position.

Gain and Offset potentiometers: The gain potentiometer allows you to either amplify or attentuate the electrical signal. The

offset potentiometer allows you to control the DC offset of the signal.

Setting gain and offset potentiometers (non-inverting unit):

1. Place a voltage equivalent to the lowest expected signal voltage on the V IN connection.

2. Adjust the offset for the desired output voltage.

3. Place a voltage equivalent to the highest expected signal voltage on the V IN connection.

4. Adjust the gain for the electrical desired output signal.

5. Repeat steps 1-4 above to verify calibration.

Setting gain and offset potentiometers (inverting unit):

1. Make sure the normal settings are already calibrated.

2. Place a voltage equivalent to the lowest expected signal voltage on the V IN connection.

3. Measure and record the output signal voltage.

4. Place a voltage equivalent to the highest expected signal voltage on the V IN connection.

5. Adjust the span such that the desired output voltage swing is obtained.

6. Place a voltage equivalent to the lowest expected signal voltage on the V IN connection.

7. Adjust the offset to achieve the desired output voltage.

Calibrating an inverting unit Example

In this example, we want to convert a 0 to 10 Vdc signal into a +5 to –5 Vdc signal.

1. While the two jumpers are at the normal setting, verify the voltmeter reads 0 Vdc at 0 Vdc input and 10 Vdc at 10 Vdc

input. If the setting do not match, calibrate potentiometers based on the above section titled “ Setting gain and offset

potentiometers (non-inverting unit)“.

2. Move the two jumpers located above the terminal strip from normal to inverted position.

3. Input a 0 Vdc signal.

4. Turn the offset potentiometer counterclockwise until voltmeter reads 5 Vdc.

5. Input a 10 Vdc signal.

6. Turn the gain potentiometer counterclockwise until your voltmeter shows –5 Vdc output.

7. Turn the offset potentiometer until your voltmeter shows 0 Vdc

8. The unit is calibrated. We recommend to go through the range and insure the desired results are obtained.
