Product Description:

The 195H4405 is a heavy-duty and durable Frequency Converter that is built to support industrial frequency conversion requirements. Made by Danfoss, its maximum output current of 4.0 A allows it to suit a range of industrial applications needing high levels of power.

This converter comes with a 3-phase power input of 380/460 V ±10%, providing stable and reliable input for high-power applications. This converter offers programmable output frequency that may be set between 0-120 Hz or 0-500 Hz, providing adjustable motor speed control for any machinery type. With a power rating of 3.2 kVA, the 195H4405 frequency converter is capable of handling loads efficiently. This converter also boasts an efficiency of more than 97% at rated load, minimizing energy loss and long-term operational costs. This converter’s ramp time can be adjusted in detail from 0.1 to 800 seconds so that users can adjust the motor accelerations and decelerations precisely. It also accepts an input current of 3.8 A, thus highlighting its high efficiency in managing power. With its durable build, the 195H4405 converter has an IP20 protection class, which means it is dust-proof and physically shock-resistant.

This 195H4405 converter is designed to perform stably in tough environments, withstanding relative humidity levels of up to 95% by IEC 721 and VDE 0160 standards. It is also rated for vibration conformity at 0.7 g, which means it can perform stably even in environments with high vibration levels. For convenient operation and monitoring, this converter has two status indicator LEDs. One indicates an alarm and one ON state, thereby giving distinct visual indications to observe its status or any error. This converter also adheres to strict EMC compliance (EN 55011, CISPR 11), thereby considerably minimizing electromagnetic interference in sensitive applications.
