Product name Power amplifier for flow pressure control valve

Model PF-DC-10

The main technical parameters:
Power supply: DC (direct current) 24/48V
Maximum output power: 24/48W
Maximum output current: 1050MA
Response speed: 0.2-5s
Load impedance: 10/40 ohms (when the load is 40 ohms,
The input voltage can only be 48V, and can only be connected between F(DC+) and GND)
Control signal input: 0~10VDC
FUSE: 3A/250V
Flutter frequency: 0-500HZ
Ambient temperature: 0~65℃
Temperature drift (maximum): 0.3mA/C

Applicable control type
Control all direct-acting and pilot-operated, overflow-type proportional pressure flow valves without electrical position feedback.
With a ramp generator, the rise and fall times can be adjusted separately, and the current limit/
Lower limit setting. Power supply wrong pole protection function. The products are all made by SMD patch technology, small size
Strong interference, good quality and low price.

English description of terminal
P(DC+) ─ Pressure input power DC24V
F(DC+) ─ Flow input power DC24V or DC48V
P=pressure GND - input power common
F=flow P+-positive pressure valve
DC=DC P- ─ negative pressure valve
F+ ─Flow valve positive
F- ─Flow valve negative
12V ─ auxiliary power supply for variable resistance
GND-control common point
P(vin) ─ Pressure input signal point
F(vin) ─ Flow input signal point

Definition of potentiometer on circuit board P(MAX) ─ Maximum pressure adjustment
P(MIN)-minimum pressure adjustment (adjusted at the factory, no need to adjust)
P(UP) ─ Pressure ramp-up time (factory adjusted to the minimum value)
P(DOWN)─Pressure ramp down time (factory adjusted to minimum value)
F(UP) ─ Flow ramp-up time (factory adjusted to minimum value)
F(DOWN)─Flow ramp down time (factory adjusted to the minimum value)
F(MAX) ─ Maximum flow adjustment
F(MIN) ─ The adjustment of the minimum flow rate (the factory has been adjusted, no need to adjust)
