Configured for power conversion and voltage regulation within industrial motor drive architectures, the Yokogawa YPHT31652-1B (YPHT31652-1B Inverter Power Supply Board) provides direct physical/electrical execution.
| Parameter | Specification |
|---|---|
| Model | YPHT31652-1B |
| Brand | Yokogawa |
| Origin | Japan |
| Weight | 0.6kg |
| Dimensions | Standard internal chassis mount layout |
| Operating Temp | -10 to 60 deg C |
| Power Consumption | Input tied to internal DC bus; output 24 VDC at 1.5 to 3.0 A |
| Core Performance | DC-DC converter with galvanic isolation, overcurrent, overvoltage, and thermal shutdown |
The board integrates galvanic isolation across its DC-DC conversion stages to protect sensitive control circuits and cooling fans from power bus transients. Precise regulation maintains a stable 24 VDC output across varying load conditions, suppressing electrical noise and preventing propagation faults into connected Yaskawa inverter control boards.
Q: Does the power supply board support active online replacement while the main drive is powered?
A: No, the drive must be fully powered down and the DC bus capacitors discharged before servicing internal components.
Q: What protection mechanisms are integrated into the output stage?
A: The circuit includes built-in overcurrent protection, overvoltage limiting, and thermal shutdown protection features.
