Frequency converter 1~220V × 3~220V 1.5-2.2 kW LEO 3.0

The PD series is a full-featured frequency converter that is suitable for small single-pump installations with constant pressure maintenance function. They are distinguished by the compactness of the housing, the dimensions of which are two times smaller than similar frequency converters from other manufacturers. The frequency converter can be installed directly on or near the pump motor due to its protection against dirt and dust (protection class IP65). The built-in single pump control function is reliable and easy to set up. Support master / slave, 2xrs485 (optional). Input: 1 Phase 220 volts Output: 3 phases 220 volts and only for connecting three-phase electric motors according to the "Triangle" scheme rated current: 10 A attention!!! The pressure sensor is not included with the frequency converter. Can be purchased additionally! Technical characteristics: Control Mode: V/F; starting torque: 1hz 100%; speed control range: 1:20; speed control error: ±1.0%; overload capacity (configurable motor overcurrent protection): 60 sec.: 120% normal.current; 1 sec.: 150% normal.current; Automatic limit current; Protection against phase loss, input/output; over voltage Protection; Types of V / F curve: linear Curve acceleration/deceleration: linear range: 0.1-3600 sec; the Starting frequency: 1~10Hz; the mains Frequency: 50/60Hz ±5%; output frequency Range: 0~50/60 Hz; inputs: 2 programmable inputs; Analog inputs: Al1:0~10V or 0/4~20mA (set by parameter); Analog power supply: configured: +5V ~ +24V (set by parameter); Source control commands: remote control input terminals; frequency: numerical tasks, PID controller; Built-in PID controller to work in a closed loop feedback control; AVR Function: maintain a constant output voltage when the input fluctuations; Preventing emergency stop: automatic control of the process of slowing down to prevent overvoltage on the DC bus at a high inertia load or rapid deceleration; LED display: displays options in the display: pressure, temperature, pressure, programmable parameters and latent functions; Automatic energy saving: automatically reduces the output voltage at low loads saves energy; password: the password can contain 4 numbers (except 0); Lock settings to prevent unauthorized changes to settings in the operation or stopped state; pressure Control: the parameters of PID controller, the control feedback PID controller in standby mode PID controller; Restart at power failure: automatic restart of the drive during a power failure, the setting delay start; Control of water leaks: optimized sleep mode to account for possible leaks; the high pressure Alarm: the feedback signal from the pressure sensor to protect the pipe network water supply from breakthrough; Signal critical pressure drop: the feedback signal from the pressure sensor to protect the pipes of water supply systems and pumps; Protection against running dry: the dry run protection (including Sensorless); installation Height: the maximum height of 1000 m, at high altitudes decrease nom.Power: 1% for each subsequent 100m; ambient temperature: -10ºC~+40ºC, rated power reduction at 40ºC ~ 50ºC 4% for each 1ºC; vibration: < 9.8 m/s2 (1.0 G); storage temperature: -10ºC~+70ºC; warranty period: 12 months.
