Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

Contact Form

A page on a website that allows users to communicate with the site owner. The page has fields for filling in name, address and type of comment. On most company websites, email and mailing addresses are also included; however, the contact form provides an immediate, convenient way for users to ask the company questions.

3PST-NO (3 Form A)

Operate Time

The time interval between the instant of the occurrence of a specified input condition to a system and the instant of completion of a specified operation.

40 ms

Coil Voltage

110VAC

Switching Voltage

The maximum switching voltage of a relay is the maximum voltage that can be across the contacts whether the relay is open or closed. Operating a relay with high voltages present can cause arcing, and this in turn erodes the contacts and eventually degrades contact performance.

690VAC - Max
