Scalar frequency converter 3.7 kW, 1F/220V (SPLC-NZE-3R7G2)

Nietz SPLC-NZE-3R7G2 scalar frequency inverter is designed for controlling the rotational speed of low-power single-phase asynchronous motors. The nominal supply voltage of the connected single-phase electric motor should be 220V, with a power not exceeding 3.7 kW (depending on the selected model).

The scalar frequency inverter can be configured and start-stop commands given through the RS-485 interface, external terminals, or directly on the operator panel, which includes an LED display, 4 indicators, 6 buttons, and an integrated potentiometer. The operator panel is removable and can be conveniently placed and mounted on the front wall of the converter cabinet (a connector must be purchased, as it is not included in the standard kit).

The Nietz NZE series inverter uses U/f scalar control and features motor slip compensation to improve performance at low rotor speeds. The output frequency can be achieved in the range of 0.1 to 400 Hz with a setting accuracy of 0.01 Hz. The device provides warnings and errors, as well as protective shutdown in the event of overheating, overload by current and voltage, under-voltage, short-circuiting, etc.

The SPLC-NZE-3R7G2 scalar control inverter casing has a protection degree of IP20 for dust and moisture, so the devices should be installed indoors, within a protective cabinet. Provisions are made for wall mounting or on a standard 35 mm DIN rail.
