GE Multilin DCP050UR_HV UR SHA High Voltage Power Supply Module

Product Brief Description

The GE Multilin DCP050UR_HV is a high-reliability HV power supply module built for the GE Universal Relay (UR) platform. It accepts wide-range AC or DC substation control power and converts it into stable regulated DC voltage to feed the relay CPU, communication circuits, I/O and protection logic. It is a critical spare part for substation protective relays and automation systems, designed to sustain reliable operation during grid voltage fluctuations.

Product Features

• HV wide input: 85–265 VAC / 88–300 VDC, 0.75A rated current
• Optimized for GE Multilin UR series relay rack, UR SHA chassis
• High EMC immunity, stable performance under substation electrical noise
• Built-in overvoltage, overcurrent, short circuit and thermal protection
• Filtered, low-noise DC output for sensitive protection and measurement circuits
• Supports redundant power configuration for no-break relay operation
• Front status LED for power health and fault indication
• Standard rack-mount form factor for simple replacement
• Rev.B upgraded hardware version for improved long-term reliability

Application Scenarios

• GE Multilin UR protective relays in medium and high voltage substations
• Transformer, generator, feeder and motor protection control panels
• Power grid automation, SCADA and substation condition monitoring systems
• Utility power plants, renewable energy collector station protection cabinets
• Oil & gas and petrochemical critical power distribution protection systems
• Retrofit and spare replacement for existing UR relay power supply units

FAQ

Q1: What does HV mean in DCP050UR_HV?

A1: HV stands for High Voltage version, supporting high AC/DC substation control power, different from LV low voltage variant.

Q2: Which relay series does it fit?

A2: It is exclusively for GE Multilin Universal Relay (UR) platform with UR SHA rack.

Q3: Can it run in redundant mode?

A3: Yes, dual power supply redundancy is supported to avoid protection trip caused by single power failure.

Q4: Can I hot-swap this module?

A4: Hot swap is allowed with redundant power; follow substation safety procedures strictly.

Q5: Can DCP050UR_HV directly replace DCP050UR_LV?

A5: No, input voltage ranges differ; match the correct HV or LV version according to site control power.
