Pressure control

Operating Voltage: 1~AC85-265V~50Hz/60Hz
Power: Max 12A/1.5KW
Temperature: Up to 60°C
Pressure: Max 1.0MPa (10bar/145psi)
Protection Rating: IP65
Starting Pressure: 0.5-7.5bar/7-108psi
(Default: 1.4bar/20psi)
Stop Pressure: 0.8-9.6bar/11-139psi
(Default: 2.8bar/40psi)
Water Shortage Pressure: 0-90% of starting pressure
(Default: 0.2bar/2psi, 0=disable water shortage detection)
Overload Current: 0-16A
(Default: 12A, 0=disable overload protection)
No-load Current: 0-80% of overload current
(Default: 1A, 0=disable no-load detection)
Water Tower Mode Interval: 1h/3h/6h/12h/24h (Default: 6h)
Water Shortage Restart Interval: 1min/30min/1h, then cycles hourly
Thread Connection: Environmentally friendly white zinc plating, standard G1/4 union (optional PC-9 base threads available)

Pressure Mode:

① Pump stops when pipeline pressure ≥ stop pressure
② Pump starts when pipeline pressure ≤ start pressure

2. Water Tower Timed Refill Mode:
① Pump stops when pipeline pressure ≥ stop pressure
② Pump starts when idle time ≥ preset interval

Both modes feature:
1> Water shortage protection:
Stops pump after 8-second delay when: 
Pipeline pressure ≤ water shortage pressure OR
Pump current ≤ no-load current
2> Overload protection:
Stops pump after 3-second delay when current ≥ overload current

 LED Indicators:

① LL: Continuous 6-hour operation alert
② CC: Frequent start/stop warning
③ OS: Pressure sensor malfunction
④ OCP: Pipeline pressure >10bar or sensor failure
⑤ OLP: Abnormal pump current
⑥ LO.0: Startup pressure value
⑦ H0.0: Shutdown pressure value
⑧ xxh: Water Tower Mode interval (01h/03h/06h/12h/24h)
⑨ F00: Water shortage pressure setting
Range: 0-90% of starting pressure (Default: 0.2bar/2psi, 0=disabled)
⑩ F01: No-load current setting Range: 0-80% of overload current (Default: 1A, 0=disabled)
⑪ FO2: Overload current setting Range: 0-16A (Default: 12A, 0=disabled)

Model Variations:

Three versions (PC-39L/PC-39/PC-39H) with identical functions but different pressure sensors:
1> PC-39L: Standard voltage-type sensor (display board and sensor must match)
2> PC-39: Domestic standard voltage-type sensor (interchangeable components)
3> PC-39H: Sensata standard voltage-type sensor (interchangeable components)

*Note: PC-39 and PC-39H components are cross-compatible

Pricing: PC-39L < PC-39 < PC-39H
