The H1 inverters were developed with industry requirements in mind. The H1 is a series of compact, high-efficiency inverters for a wide variety of applications. Thanks to removable control terminals, ability ot use an external panel and side-by-side installation, the H1 series is easy to install and maintain. The inverter can realize U/f or SVC control and have a built-in PID regulator.
- operation modes:
- U/f
- SVC
- compatible with asynchronous, synchronous and single-phase motors
- maximum frequency of 1000 Hz
- improved heat dissipation allowing side-by-side installation
- low-power units can be mounted on a TS35 rail
- short-circuit protection, phase loss protection, overload protection
- STO safety input
- compatible with Modbus RTU
- built-in PID regulator
- automatic voltage and current limiting
Input/Output
- 10 binary inputs – NPN or PNP
- 2 analog inputs – current or voltage
- 3 relay outputs
- 2 analog outputs – current or voltage
- 1 three-wire STO safety input
