i series e Overview
The i series e and i series Quad dimmer racks are composed of three main modular components:
1.
The dimmer rack chassis
2.
The dimmer modules
3.
The control module
The dimmer rack chassis
defines the number of dimmer modules that may be installed, the power feed line
voltage, and power feed configuration of the installation.
•
i series e
racks are available in 96,48, and 24 dimmer channel configurations, for either 90-135 VAC or
190-260VAC power feeds, in either 3 phase - 4 wire Y plus ground or single phase 3 wire plus ground
power feed configurations, with an alternating current line frequency in the range of 47 to 63 hertz. i
series e racks have a number of bussing configurations that allow racks to be bussed together with
ratings between 10,000 and 100,000 AIC capacity depending on the configuration.
•
i series quad
racks are available in 48 channel and 48 or 96 channel portable dimmer configurations, for
either 90-135 VAC or 190-260VAC power feeds, in either 3 phase - 4 wire Y plus ground or single phase
3 wire plus ground power feed configurations, with an alternating current line frequency in the range of
47 to 63 hertz.
The dimmer modules
define the power and filtering levels of the individual branch circuits to be controlled.
Dimmer modules of different power capacities are mechanically keyed so that dimmer modules of higher
ampacities may not be inserted in to dimmer slots wired for lower ampacities. A wide variety of dimmer and
are available.
•
For 120VAC systems,
i series e
dimmer modules come in either dual or single channel module
configurations, with either 500micro second or 800 micro second rise times.
•
For 240VAC applications,
i series e
dimmer modules come in either dual or single channel module
configurations, with either 350micro second or 500 micro second rise times.
•
For 120VAC systems,
i series quad
dimmers are only available in 4 circuit 2.4KW or 1.8KW
configurations with 350 microsecond rise times.
•
For 240VAC systems,
i series quad
dimmers are only available in 4 circuit 4.0KW configurations with
270 microsecond rise times.
It should be noted that
in order for the dimmer modules to cool properly, the rack must have all the
dimmer module positions installed in the rack with either a dimmer module or airflow module.
The control module
contains nearly all of the control electronics and generates the necessary control
signals and power necessary to control the dimmers in the rack. There are 2 different control modules for
i
series e
and
i series quad
.
•
The i96/48 control module (CTP-0311e) controls i96e, i48e or i48Quad dimmer racks in all configurations.
•
The i24 control module (CTP-0313e) controls i24 dimmer racks in all configurations.
Control modules are completely interchangeable within the i series e and i series quad system, as long as
they are the same type of control module as detailed above. The only selection that makes a control module
unique is the thumbwheel address setting on the front of the control module. All other individual
parameters for the rack are stored in the socketed serial EEPROM chips on the i series e backplane. On
power up, the control module automatically loads all the unique information from the serial EEPROMS on the
