Description

The GE URSHA is a third‑generation high‑voltage power supply module engineered by Multilin for the Universal Relay (UR) series. Providing up to 45 W of stable power, the GE URSHA directly replaces older UR‑1H and UR‑RH units while offering higher efficiency and greater reliability. Its rugged design includes over‑temperature shutdown, improved isolation, and extended temperature range, making the GE URSHA a direct drop‑in upgrade for all UR applications.

Applications

All UR series protective relays (UR5xx, UR6xx, UR8xx, etc.) as the main power source
Substation & utility automation as a reliable power source for protection panels
Industrial control rooms as a power supply for critical relay systems
Harsh environment installations requiring conformal coating and wide temperature support

Features

Higher output power – 45 W (vs 35 W of previous generations)
Direct drop‑in replacement – backward compatible with UR‑1H and UR‑RH
Wide input range – 88–400 V DC for global utility applications
Enhanced reliability – only one electrolytic capacitor (was 27), up to 40‑year life
Conformal coating – protects against humidity and dust

Functions

Provides primary DC operating power to the entire UR relay unit.
Supplies 48 V DC dedicated to the relay’s dry contact inputs.
Continuously monitors all internal voltage rails for diagnostic purposes.
Delivers hold‑up power during short‑term AC disturbances to maintain relay operation.

FAQ

Q1: Can the GE URSHA replace my old UR‑RH?
A1: Yes. The GE URSHA is a direct, drop‑in replacement for UR‑1H and UR‑RH power supply modules without any hardware changes.

Q2: What is the output power rating of the GE URSHA?
A2: The GE URSHA delivers up to 45 W of continuous power, a 28% increase over the 35 W of previous generations.

Q3: Does the GE URSHA support hot‑swap?
A3: Yes. It is fully hot‑swappable, allowing replacement without powering down the relay.

Q4: What is the operating temperature range?
A4: The GE URSHA operates reliably from –40 °C to +70 °C, suitable for both outdoor and harsh industrial environments.

Q5: Are there different versions of the GE URSHA?
A5: Yes. The “‑A” suffix designates a horizontal 19‑inch rack mounting with conformal coating. A “‑B” suffix indicates a vertical 3/4‑size rack mounting.
