STEVAL-VP26K02F

Evaluation board implements a double output isolated SSR flyback specifically designed to supply smart meter and PLC systems. The evaluation board has been developed using the VIPER267KDTR offline high-voltage converter which features a 1050V avalanche-rugged power section, PWM operation at 60KHz with frequency jittering for lower EMI, current limiting with 700 mA fixed set point, on-board soft-start, safe auto-restart after fault and low standby power. The power supply provides 12V at 700mArms (1A peak) to the power line modem (PLM) and the analogue circuitry, and 6 V at 200 mA to supply digital circuitry and other low voltage parts. The power supply is designed to operate across a three-phase input mains from 50 to 290VAC but can also be connected to a single phase mains from 85 to 500VAC.

• Secondary side regulation (SSR)
• EMC with EN55022, EN61000, EN61000-4-4, EN61000-4-5, EN61000-4-6
