48VDC Direct Current Voltage Specification

Feature & Principle

48VDC is a common nominal DC supply voltage. It provides stable direct current for field transmitters, protection relays, communication modules and telecom equipment. It has good anti-interference performance, usually negative earth in telecommunication systems.

Specifications

Model: 48VDC Nominal voltage: 48V DC Typical range: 42~58V DC Application: Instrument, relay, communication, remote I/O, SCADA cabinet Certification: N/A

Components & Diagnostics

This is an electrical parameter instead of physical spare part. Common abnormal conditions: overvoltage, undervoltage, ripple too large, short circuit, reverse polarity damage.

Product Brief

48VDC voltage specification, standard DC power parameter widely used for instrument and communication spare matching.
