Basler Electric 9488800100 AVC Sensing Module

INTRODUCTION

The AVC Sensing Module provides a convenient and cost-effective method

for expanding the applications where AVC63-12 and AVC125-10 voltage

regulators can be applied. The AVC Sensing Module increases the nominal

sensing voltage of style BX AVC63-12 and AVC125-10 voltage regulators

from 200/240 Vac to 480 Vac or 600 Vac. The AVC Sensing Module is

compatible with nominal sensing frequencies of 50/60 Hz and 400 Hz.

A compact, rugged (potted) case enables the AVC Sensing Module to be

mounted directly on the generator.

Other than making connections during installation, the AVC Sensing Module

requires no adjustment or calibration.

The AVC Sensing Module is housed in a potted, plastic case that can be

mounted in any convenient position.

Overall module dimensions and panel drilling dimensions are illustrated in Figure 1.

Mounting Hardware

The AVC Sensing Module can be mounted directly on a genset using #10-32 or

equivalent hardware. A lock washer should be used between the screw head and

body of the module. Torque applied when tightening the mounting hardware

should not exceed 25 inch-pounds (2.8 N•m).

CONNECTIONS

All AVC Sensing Module connections are located on the back panel. Sensing voltage

is applied to the lower, six position terminal block. Sensing voltage is supplied to the

voltage regulator from the upper, three-position terminal block. Connections consist

of #6 terminal screws. Each terminal accepts a maximum wire size of 12 AWG (13

mm2). When securing connections, apply no more than 9 in-lb (1 N•m) of torque to

each terminal screw.

Before connecting the module, review the terminal descriptions listed in Table 1 and

the connection diagram of Figure 2. At any given time, only one of the two sets of 

sensing voltage input terminals can be used. Under no circumstance can both the

480 Vac and 600 Vac sensing input terminals be connected to a voltage source.

MAINTENANCE

A periodic inspection of the AVC Sensing Module should be made to ensure that all

connections are clean and tight.

The AVC Sensing Module contains no serviceable parts. If a failure occurs, replacement

of the module is recommended.
