Product Code : SCL-EELE-13121
Indian Lab Suppliers supplies the Regulated DC Power Supply with DC Distribution Panel (Product ID: 13121) as part of its electronics engineering lab equipment range. It is a three-phase, fully controlled thyristor converter that supplies regulated, adjustable DC to the armature and field of a DC motor.
Quick Answer
The unit takes 415 V (±10%), 50 Hz (±2%) three-phase four-wire supply and gives up to 440 V DC for the armature and 220 V DC for the field. Speed is held within ±2% using armature-voltage feedback, with tacho feedback as an option, and soft start with acceleration and deceleration adjustable from 5 to 30 s. The converter is built as input, thyristor, regulation, output, excitation, indicating and protection modules and is forced-air cooled. Output currents are not stated, and the description is of a motor drive, so please confirm the output ratings and whether a DC distribution panel is included at quotation.
