About the S20-204P2B1000
Reliance Electric manufactures S20-204P2B1000, a 3-phase SP200 AC drive that is 7.17 in (height) x 2.95 in (width) x 1.38 in (depth). This drive weighs 0.48 kg and has a 3-phase 200-240V input and a 3-phase 460V output. The drive is rated at 4.2A (1.0 HP). There are 3 different control models to match specific needs. Model A is a Single Channel Analog for control from one analog signal or a speed pot. Model B is a preset speed for up to 8 specific speeds that are controlled by 3 ON/OFF digital inputs. Model C is a Dual Channel Analog for applications that can take advantage of an operation between two analog signals. For Model C, the user may choose from PI, add, or multiply functions. This unit is control model B, as noted in the model number.
The humidity for this drive must remain between 0 and 955 non-condensing relative humidity. For the control inputs, the rated voltage is 10 VDC to 24 VDC (plus or minus 10%), the load for each input is 10 mA minimum and 20 mA maximum, and the maximum allowable off state leakage current is 1.5V/2.0 mA. The operating performance of this drive is an input frequency resolution is 0.4% analog and 0.1 Hz digital, the output frequency resolution is 0.1%, the output voltage regulation is 3%, and the minimum power dip control ride through time is 100 msec. The relay output involves a rated current and voltage of 0.5A maximum at 125 VAC and 1.0 maximum at 30 VDC.
