The J series is EVEVSPOWER’ plastic-housed buck converter family (J1, J2, J3). These compact modules step a wide DC input down to a stable regulated output with low quiescent current and adjustable soft-start, making them a dependable choice for low-power rails in industrial equipment, home appliances, portable electronics and communication devices.
Key Features
- Wide input voltage range (typically 8–80V DC)
- High conversion efficiency with low standby power
- Adjustable soft-start; short-circuit hiccup / constant-current modes optional
- Compact plastic housing, easy mounting
