Product Description

MICROMASTER 420 Types Variable Frequency Drive Inverter Pumps Inverter

Application

The MICROMASTER 420 inverter is suitable for a variety of variable-speed drive applications.

It is especially suitable for applications for pumps, fans and conveyor systems.

It is the ideal cost-optimized frequency inverter solution. The inverter is especially characterized by its customer-oriented performance and ease-of-use. Its large supply-voltage range enables it to be used all over the world.

Design

The MICROMASTER 420 has a modular design. The operator panels and communication modules can be easily exchanged without requiring any tools.

Main characteristics

Easy, guided start-up
Modular construction allows maximum configuration flexibility
Three fully programmable isolated digital inputs
One scalable analog input (0 V to 10 V) can also be used as a 4th digital input
One programmable analog output (0 mA to 20 mA)
One programmable relay output
30 V DC/5 A, resistive load
250 V AC/2 A, inductive load
Low-noise motor operation through high pulse frequency, adjustable (observe derating if necessary)
Complete inverter and motor protection

Mechanical features
