Description

UNS4681V511 is a product of ABB company, with the full model name UNS 4681 Var.511 3BHE004074R0511. It can serve as an auxiliary contact module or a power module for circuit breakers. Detailed information is as follows:

As an Auxiliary Contact Module for Circuit Breakers

1. Function: Used for ABB circuit breakers, providing additional contact signals to obtain the current status information of the circuit breaker, such as open, closed, or fault. This module supports high-precision and high-speed monitoring capabilities, allowing quick response to changes in circuit breaker status.◦

2. Technical Specifications: Contact type is SPDT, providing 2 normally open contacts and 2 normally closed contacts, with a rated contact current of 10A, a contact lifespan of 1 million operations, operating temperature range of -25°C to +70°C, protection rating of IP20, DIN rail mounting, compliant with IEC 60947-5-1 standard.

As a power module:

1. Function: It can be directly mounted on a printed circuit board to convert the input AC or DC power into stable DC power to supply other circuits.

2. Technical specifications: Based on output accuracy, it can be classified into regulated output and adjustable output (AC-DC power modules), unregulated output, regulated output, and adjustable output (DC-DC power modules); based on isolation voltage, it can be divided into different levels, such as AC-DC power modules with isolation voltages of 2000V, 3000V, 4000V, etc., and DC-DC power modules with isolation voltages of 1000V, 1500V, 3000V, 6000V, etc.

3. Application fields: Suitable for communication power supplies, such as program-controlled switches, transmission equipment, data centers, mobile base stations, etc.; industrial control power supplies, such as automated production lines, robots, sensors, actuators, etc.; computer and peripheral power supplies, consumer electronics power supplies, and more.
