Leprecon LD-340 DMX Series - Manual (Page 3)

Specifications
Power Capacity
The LD360 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:
LD360 DMX:
Pack Limit: 15 Amps
20 Amps with approved plug.
LD360 DMX-HP
Pack Limit: 15 Amps per line cord.
As indicated, the total pack power of the LD360 DMX can be increased to 20 amps by
changing the factory supplied 15 amp power plug to a type approved for the higher power.
Some of the choices are:
Plug Mating Socket Type
Nema 5-20P Nema 5-20S “Tee blade”
Hubbel 5364VY Hubbel 5369VY
Hubbel 5366C Hubbel 5369C
Nema L5-20P Nema L5-20S Twist Lock
Hubbel 2311VY Hubbel 2313VY
Hubbel 2311 Hubbel 2311
Control input
The LD360 DMX accepts DMX 512 1990 as specified by USITT. DMX signal requires the use of
cable rated for data communication at 250K baud; for this reason the use of microphone cable is
NOT recommended. DMX rated cables are available pre-manufactured from your Leprecon
dealer. For more information on the DMX standard and acceptable cable, see the Appendix of this
manual.
For convenience, two connectors are provided on the LD360DMX. This allows easy connection to
additional dimmer packs. The DMX standard allows up to 32 dimmers to be connected to a single
DMX controller.
For proper operation, it is recommended that the last dimmer in the system includes termination
for the DMX signal line. This termination is nothing more than a 120 ohm resistor installed across
pins 2 and 3 of the 5 pin XLR. For your convenience, a male 5 pin XLR with such a resistor in
place is available as an accessory from your Leprecon dealer.
