The Macromatic PBDU is a multi-detection phase monitor relay. This slim housing DIN-Rail mount relay has a monitored voltage range of 208-480V AC. It monitors against 3 different types of phase errors and has an output of 5A SPDT. It has two LED indicators. The green LED shows the power to the relay is on and the yellow LED shows the current status. The slim housing saves space on the DIN-Rail.
Note: Image is an approximation. Actual part may differ.
Monitors For:
- Phase Loss
- Phase Reversal
- Phase Unbalance (can be disabled if needed)
Specifications
- Relay Function- Multi-Detection 3 Phase Monitor
- Monitored Voltage- 208-480V AC
- Output- 5A SPDT
- Min. Voltage- 187V AC
- Max. Voltage- 528V AC
- Power Consumption- 10VA (1 watt) @ 400 / 50Hz, 16VA (1.5 watt) @ 480V / 60 Hz
- Phase Loss- Trips on Phase L1, L2, or L3 loss
- Phase Reversal- Trips if rotation is something other than L1-L2-L3
- Phase Unbalance- Adjustable from 5-25% unbalance
Trips when one of the 3 lines diverges from the average of all 3 by more than the adjusted set point for longer than the trip delay
- Trip Delay- 100 milliseconds
- Accuracy- < / = 5%, Repeat Accuracy: + / - 2%, Temperature Influence: < / = 0.05% (Celsius)
- Operating Temperature- -25 C to 55 C (-13 F to 131 F)
- Storage Temperature- -25 C to 75 C (-13 F to 167 F)
- Output Contacts- SPDT 5A @ 250V AC
- Life- Mechanical: 20,000,000 Operations
Electrical: 200,000 Operations at 1000VA resistive load
- Humidity- -15 to 85%
- Termination- 1 x #14-20 AWG, 2 x #16-20 AWG
- Dimensions- 3.4" Height x 0.7" Width x 2.6" Depth
- IP Rating- IP 20 (protected from outside particles 12.5 mm (0.5") in diameter or greater)
- Approvals- UL & CUL Listed, CE
The PBDU de-energizes and the yellow LED turns off when any of the phase errors are detected, after a 100 millisecond trip delay. It will energize again automatically once the error is corrected, and the yellow LED indicator will come back on. Trip delay is fixed.
