IES Ethernet PowerModule Operators’ Manual v1.4 Isine 2
1 Introduction
1.1 Product range
This handbook describes the operation and
programming of the IES PowerModule range of
Isine dimmers incorporating sinewave dimming
technology. Sinewave dimming produces a pure
sinewave output for a lighting load. The intensity
of the light is controlled by the amplitude of the
sinewave. Other dimmer technologies (traditional
phase control and IGBT reverse-phase) control
the lights intensity by chopping the mains
waveform, which can cause acoustic noise and
electrical interference problems. The dimmers
covered by this handbook are:
2234 PowerModule PM80S
1 x 1.2 kW, 1 x 80 V
2102 PowerModule PM2-2S
2 x 2.5 kW, 22 A single phase
2235 PowerModule PM1-5S
1 x 5 kW, 22 A single phase
2103 PowerModule PM4-2S
4 x 2.5 kW, 44 A single phase
2104 PowerModule PM2-5S
2 x 5 kW, 44 A single phase
2236 PowerModule PM6-2S
6 x 2.5 kW 22 A three phase
2237 PowerModule PM3-5S
3 x 5 kW 22 A three phase
2105 PowerModule PM12S
1 x 12 kW 52 A single phase
2237 PowerModule PM24S
1 x 24 kW 104 A single phase
1.2 New dimmer technology
The PowerModule range of dimmers represents
the most advanced dimming system available
today. The advantages of Isine dimming
technology, as developed by IES in its Isine
design, deliver low-noise, high power dimming
capability with advanced electronic measurement
and control to accommodate variations in the
power supply and load conditions. The dimmers
will automatically compensate for poor mains
regulation, and will respond to a short-circuit faster
than any mechanical protection device.
1.3 Distributed dimming
The high efficiency (low heat dissipation) of the
dimmer circuit, combined with its compact design,
electronic protection and sophisticated status
reporting system, makes the PowerModule ideally
suited to distributed dimming schemes where a
central dimmer room is unavailable or undesirable.
1.4 Key features of Isine system
The Isine system offers low noise dimming (both
acoustic noise from lamp and dimmer as well as
electrical interference are reduced), control of a
wide range of load types, and sophisticated
control options for the broadest range of
applications. Each dimmer channel can be
individually programmed either at the dimmer
itself, or remotely from a PC, and once
programmed, the dimmer can operate simply and
transparently whilst being protected against
inadvertent adjustments. The PowerModule range
is compatible with all other IES dimmers including
the Executive Isine dimmer pack.
1.5 Ethernet connectivity
The Ethernet module supports DMX over Ethernet
and provides extensive configuration facilities
which are described in Chapter 9 ‘Ethernet
module’.
2 Unpacking and installation
2.1 Unpacking & checking
The PowerModule is self-contained and only
requires mounting components (two hook clamps
or ‘C’ clamps and a safety bond), and a suitable
mains input connector. The PowerModule is
packed to withstand normal transportation, but
before operating the unit, check there is no sign of
transit damage which could affect the operation
and safety of the dimmer.
2.2 Positioning
The PowerModule is an extremely versatile
dimmer, and can be located in a variety of
positions. It is designed for natural convection
cooling, hanging by two suspension clamps and
care must be taken to ensure adequate ventilation
around the case. Note that full-power operation is
only possible if the PowerModule is suspended in
free air. If it is used on the ground there may be
insufficient ventilation for continuous service at full
power. Should the PowerModule overheat in this
condition, an internal detection circuit will report an
overheat condition and will progressively reduce
power until a normal operating temperature has
been reached.
2.3 Connections
2.3.1 Mains connection
If the PowerModule is fitted with a cable then
attach a suitable connector to the cable. If the
PowerModule is fitted with a connector then
provide a suitable power cable with mating
connector. All connections should be made by
qualified personnel.
2.3.2 DMX data signals
All PowerModules are controlled by DMX 512
connected by a shielded two-pair high-speed data
cable with XLR 5-pin connectors (male = input;
female = output).
