The STEVAL-VP26K02F evaluation board implements a double output isolated SSR flyback specifically designed for industrial application supplied from 3-phase input.
The evaluation board has been developed using the VIPER267KDTR offline high-voltage converter which features a 1050 V avalanche-rugged power section, PWM operation at 60 kHz 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 12 V at 700 mArms (1 A peak) for the analog 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 290 VAC but can also be connected to a single phase mains from 85 to 500 VAC.
Key features:
- Double output voltage: 12 V at 0.7 Arms (1 A peak) and 6 V at 200 mA
- Secondary side regulation (SSR)
- Extended AC mains input voltage range: 85 to 500 VAC
- EMC with EN55022, EN61000, EN61000-4-4, EN61000-4-5, EN61000-4-6
- WEEE compliant
- RoHS compliant
