This page lists official electrical and physical specifications of the Argon (servo drive).

Physical

Property Value Units
Dimensions (with wall mounting tabs)¹ TBD mm
Dimensions (excluding wall mounting tabs)¹ TBD mm
Weight TBD kg
Case materials Steel (cover), aluminum (heat sink)

¹) Wall mounting tabs are fixed part of enclosure

Electrical

General

Property Value Units
Operating temperature 10-70 °C
Storage temperature -30-90 °C
Humidity 0-95 non-condensing  %
Power dissipation 2-100¹ W

¹) Power dissipation is output current and input voltage related.

Power supply

Supply Input voltage Input current typ Input current max
Logic power 24 VDC +/- 10% 0.1 - 0.4 A 0.5 A
Motor power 85 - 264 VAC 50/60 Hz 0 - 15 A¹ 26 A¹
84 - 380 VDC 0 - 15 A¹ 26 A¹

¹) Estimating true current or power consumption based on this table may be difficult as current demand typically varies greatly and and almost completely depends on motor load conditions.
