General Information
1. General Information
1.1 Introduction
Chroma AC source model 64180/64270/65180/65270 are designed to get larger 3-phase AC
power. They are assembled by 3 units of nowaday model 6460/6490/6560/6590. Each unit is
used as one phase output. This manual only describes the installation, operation and theory
specially for 64180/64270/65180/65270 programmable AC source. The detail specification and
operation, please refer to the user’s manual of 6460/6490 or 6560/6590.
1.2 Description
For model 64180/64270/65180/65270 AC sources, although the model name and appearance are
looked almost the same with 6460/6490/6560/6590, the inner F/W and connected cables are
different. There is one Master and two Slaves in the three units of 64180/64270/65180/65270.
It is impossible to use individual unit as totally the same as 6460/6490/6560/6590. The Master
unit can be used individually, but the slaves only can used with the Master together.
In order to help users to operate 64180/64270/65180/65270 AC sources as conveniently as
possible, Chroma offers a softpanel. It is a easy-use remote control interface. Users can
operate on the computer with GPIB interface.

2. Installation
2.1 Preparation for the Use
Although Chroma AC source model 64180/64270/65180/65270 are assembled by 3 units of
nowaday model 6460/6490/6560/6590, the F/W and connecting cables are different. Chroma
has install the 64180/64270/65180/65270 F/W before shipping by your order. And the
accessories includes connecting cables and input breaker.
Before begins the instrument must be connected with an appropriate AC line input. As the
instrument is cooled by fans intelligently, it must be installed in an area with sufficient space for
air circulation. It should be used in an area where the environment temperature does not exceed
40°C.
2.2 Requirements of Input Power
2.2.1 Ratings
Input Voltage Range: 190-250 VLL, 3 phases 4 wires ∆, or
329-433 VLL, 3 phases 5 wires Y
Input Frequency: 47-63 Hz
Max. Current/Phase: 64180/65180 : 50 A
64270/65279 : 70A
aCaution
The AC source can be damaged if it is operated at an input voltage that is beyond its configured
input range.

2.2.2 Input Connection
The input terminal block is located on the instrument rear panel. The power cord must be rated
at least for 85°C. The power line input must have a current rating, which is greater than or
equal to the maximum current rating of the AC source.
aCAUTION
There are two input voltage rating models, one is 380 VLL3 phases 5 wires (Y), and the other is
220 VLL 3 phases 4 wires (∆). Be careful to verify the model you have, and make sure that the
main voltage is suitable for the model.
See Figure 2-1 and do the following steps one by one:
1. Remove the safety cover from the back of AC source.
2. Open the line clamp on the safety cover, and screw on the power cord to the instrument
through the cable gland.
3. Position the power cord, and tighten the cable gland to secure the clamp.
4. Connect the ac lines to the terminal blocks of the AC source as Figure 2-2 shows.
5. If you need to connect the load to AC source, please refer to section 2.4 for output
connection.
6. Slip the safety cover over the ac input terminal strip, and secure the cover with two screws.
+WARNING
To protect operators the wire connected to the GND terminal must be connected to the ground.
Under no circumstances shall this AC source be operated without an adequate ground connection.
Installation of the power cord must be done by a professional in accordance with local electrical
codes.
