abstract = {{The performance of any particle accelerator like cyclotrons largely depends upon the dc precision of the magnetic field of various electromagnetic devices present in the system. The precision magnetic field of the electromagnets in turn are being generated using current regulated power supplies having output current stability ranging from 10ppm to 100ppm as per the beam dynamics and transport requirement. An embedded EPICS based power supply control module is developed as a part of indigenous precision power supply development activity in VECC. The module is designed using an ARM based single-board-computer interfaced with 16bit DAC, 16bitADC and 16 numbers of isolated digital input-outputs. The digital inputs are designed to be interrupt enabled to minimize the response delay. The development of EPICS IOC involves development of device driver for DAC, ADC and digital input and output. The developed module is incorporated in a prototype dc, ±10A / ± 100V, 100ppm stability class, switch-mode type true-bipolar power supply, to be used for the steering magnets of the beam transport line of K-130 Cyclotron. This paper describes the detailed design and testing of the module.}},
