Description

The OP1490 boxes provide the following features to the OP1400 series test benches:

• 12V auxiliary supplies for the OP8110 amplifiers
• Start/Stop button to activate or deactivate the 3 phase 400V/480V supply to the DC power supplies
• Emergency stop interface to quickly isolate the test bench's power path (excluding monophasic power bars) from all energy sources

Functional Overview

Models

There are various models of the OP1490 box to meet the needs of the different models of OP1400 Series test benches. They are detailed in the table below:

Controls and Indicators

Emergency Stop Button

The emergency stop button allows to quickly secure the test bench in urgent situations. It is hard wired to an emergency stop loop that energizes the contactors inside the OP1460/1480 boxes and inside the PDU. When the user pushes on the emergency stop button, all these contactors become unsupplied and this effectively isolates the test bench's power path (excluding monophasic power bars) from all possible sources of electrical energy. The button will remain depressed once it has been pushed down, the user must then rotate the button clockwise to reset the emergency stop loop. The emergency stop button can be secured with a padlock if desired.

Start/Stop Button

These buttons allow to control the 3 phase 400V/480V supply to the DC power supplies of the test bench. An indicator light located between the Start and Stop buttons lights up when activated.

Status LEDs

The status LEDs provide with the following visual information:

Fuses

User replaceable fuses to protect against overloading of the auxiliary supplies. Replace only with fuses that have the proper rating (as indicated on the equipment).
