DC3R-12D-00-010-AI | Reliance Electric Regenerative Drive

Description 

The DC3R-12D-00-010-AI, categorized under Reliance Electric's DC3 series regenerative drives, is encapsulated within a chassis enclosure denoted by the "00" designation. The "AI" specification signifies the inclusion of an isolated reference input spanning 0-10 VDC and 4-20 mA. Detailed guidelines for installation and operation are provided in the accompanying user manual. 

Key operational parameters include a maximum speed trimpot adjustment range of 0-90% of the rated voltage, with a corresponding minimum speed trimpot adjustment range of 0-25%. Acceleration and deceleration times range from 0.5 to 6 seconds under varying load conditions. Forward and reverse torque capabilities extend up to 200% of the rated current. 

Input impedance across S0 to S2 terminals measures at 32 k ohms, while the maximum field current is specified at 1 ADC. AC line distribution capacity reaches a maximum of 25 KVA with a 115 VAC input and 50 KVA with a 230 VAC input. Field voltage output varies, with 115 VAC yielding 50 VDC from F1 to L1 and 100 VDC from F1 to F2, while 230 VAC results in 100 VDC from F1 to L1 and 200 VDC from F1 to F2.

Information About DC3R-12D-00-010-AI

The DC3R-12D-00-010-AI, belonging to Reliance Electric's DC3 series of regenerative drives, is encapsulated within a chassis enclosure, indicated by the "00" designation. Additionally, the "AI" designation denotes the drive's provision of an isolated reference input spanning 0-10 VDC and 4-20 mA. Comprehensive guidance on installation and operation procedures is available in the accompanying user manual. 

Key operational parameters include a maximum speed trimpot adjustment range of 0-90% of the rated voltage, complemented by a minimum speed trimpot adjustment range spanning 0-25% of the rated voltage. Acceleration and deceleration times range from 0.5 to 6 seconds under varied load conditions, with a maximum forward and reverse torque capability of 200% of the rated current. 

The drive exhibits an input impedance of 32 k ohms across terminals S0 to S2, while the maximum field current is capped at 1 ADC. In terms of AC line distribution capacity, the drive supports a maximum of 25 KVA with a 115 VAC input and 50 KVA with a 230 VAC input. Field voltage output varies based on input voltage, with 115 VAC yielding 50 VDC from F1 to L1 and 100 VDC from F1 to F2, and 230 VAC resulting in 100 VDC from F1 to L1 and 200 VDC from F1 to F2. 

Operating within a speed range of 60:1, the drive exhibits speed regulation under load change conditions, achieving 1% or better of the base speed with armature feedback and 0.1% of the base speed with tachometer feedback. Operational vibration limits are specified, with a maximum allowable vibration of 0.5 g below 50 Hz and 0.1 g above 50 Hz.
