3G3JV-AB004

Omron's 3G3JV-AB004 adjustable frequency drive provides a single-phase input voltage ranging from 200 to 240 V with a frequency standard of 50/60 Hz. The rated output current reaches 3 A, and the maximum output voltage provided is adjustable on a 3-phase basis, peaking at between 200 and 230 V, depending on the input.

The operational frequency range for this drive extends from 0.1 to 400 Hz, with a frequency accuracy of ±0.01% when using a digital reference. For analog references, the accuracy is ±0.5%. The frequency setting is highly precise, allowing adjustments of 0.01 Hz for frequencies under 100 Hz, and broader increments of 1 Hz for frequencies of 100 Hz and above.

An overload capacity is built into the system, allowing for up to 150% of the rated output current for a duration of one minute. Additionally, both acceleration and deceleration times are independently adjustable within a range of 0.1 to 999 seconds. This versatility in programming enhances user control over motor behavior and response.

The braking torque performance is also noteworthy, allowing for higher short-term average deceleration torques across various horsepower ratings. Protection against motor overload is ensured through an electronic thermal overload relay.

Cooling is typically achieved via a built-in fan for models rated for 230 V and 1 HP, while other configurations utilize self-cooling mechanisms. The unit's enclosure is rated as open chassis with an IP20 classification, providing a degree of protection ideal for environments where dust and moisture are not critical issues.
