Output frequency: V/F: 0-100Hz
Operation command channel: 3 channels: operation panel given, control terminal given, serial communication port given, can be switched in a variety of ways
Frequency source: analog voltage given, analog current given, serial communication given, etc., can be switched in a variety of ways
Analog power supply: 5V/10V/24V three power supply voltages, use most sensors
Input terminals: 3 digital input terminals; 2 modular input terminals; 2 communication terminals, RS485 one channel, CAN one channel
Output terminals: 1 digital output terminal; 1 group of relay output terminals

Built-in PID: can easily realize closed-loop control system
AVR function: when the grid voltage changes, it can automatically keep the output voltage constant
Overvoltage and overspeed loss: automatically limit the current and voltage during operation to prevent frequent overcurrent and overvoltage tripping
Fast current limiting function: minimize overcurrent faults and improve system stability
Power-on peripheral equipment safety self-check: can realize safety detection of powered peripheral equipment such as grounding, short circuit, etc.
Power-on automatic start function: power-on automatic start is optional, start delay is adjustable
Automatic energy saving function: automatically reduce the output voltage under light load to achieve energy saving effect
Constant voltage control function: PID adjustment, PID feedback disconnection check, PID sleep and wake-up
Multi-connection working mode: multiple units can be connected through the connection terminal. Realize multi-pump connection mode
Upper computer communication function: remote equipment maintenance can be performed through an external GPRS monitoring module
Anti-freeze function: frequency, time, and cycle can be set for anti-freeze function control
Water leakage detection: optimize sleep control through water leakage detection coefficient

LED display: can display feedback pressure, target pressure, operating frequency, operating current and other data
Parameter lock function: define whether the parameters are locked in the running or shutdown state to prevent misoperation

Place of use: can be used indoors and outdoors, prevent direct rain, no corrosive gas, flammable gas on site
Altitude: below 1000m; above 1000m, use with derating, 1% for every 100m increase
Ambient temperature: -10℃ ~40℃, derating is required when the temperature exceeds 40, 1% for every 1% increase in ambient temperature, the maximum ambient temperature is 50℃
Humidity: 95%RH, avoid condensation
Vibration: vibration acceleration is less than 0.6g
Storage temperature: -25℃ ~ +60℃
