Introduction
The new ULD series dimmer is designed to be a capable and reliable solution for
temporary and portable dimming requirements. With the menu-based interface, the
dimmer can be configured for different applications, including stand-alone use
without a controller. Default values can be restored at any time, clearing the internal
memory back to the standard values.
Please take a few minutes to review the specifications and operating features of the
ULD-360 dimmer.
The ULD-360 dimmer is designed for use with conventional incandescent fixtures.
Transformer loads, such as low voltage devices using a step-down transformer, may
require an additional load to be connected to the same circuit to operate properly.
For operating florescent fixtures, see the section regarding Front Panel Controls.
2) Specifications
Power Connection
Unless otherwise indicated, your ULD-360 dimmer is designed for connection to
standard US power systems, 120 VAC 60 Hz. Lamp connections must be 120 V
devices only. Line voltages over 135 VAC will trigger the overvoltage protection
circuit and shut off the dimmer pack.
Ambient Temperature
The ULD-360 dimmer is designed for use in a cool, ventilated area. Ambient
air temperature must be less than 40 degrees Celsius, or about 104 degrees
Fahrenheit.
Power Capacity
The ULD-360 DMX is unique in the market of small portable dimmers. A single
breaker is used on the pack instead of individual fuses per each channel. As a
result, the limits of the dimmer are
pack
limits, not channel limits. The following
guidelines should be followed:
ULD-360 DMX
Pack Limit: 15 Amps
ULD-360 DMX-HP
Pack Limit: 15 Amps per line cord, or 30 amps total
