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-340 dimmer.
The ULD-340 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-340 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-340 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 ULD340 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:
ULD340 DMX-HP – when plugged into a 100% duty-cycle service or a wall
socket in the USA
Pack Limit: 15 Amps (1800 watts) for each of the 2 power input cables, or 30
amps (3600 watts) total
Individual channel limit of 1800 watts
