1.0 Introduction

The JANDS FP12 is a high quality, rugged, 12 channel, 2.4kVA per channel (10A/240V)
dimmer ra ck specifically de signed fo r demand ing tou ring and thea tre ap plications.

The FP12 can be powered from three-phase or single-phase mains supplies. The FP12
features opto-controlled Triacs and medium risetime chokes protected by
thermal/magnetic circuit breakers. The FP12 uses microprocessor-based digital control
for accurate dimming a nd in -built tes t funct ion s. Dig ital control is v ia stand ard DMX-51 2
protocol.

The FP12 features toroidal output chokes. These chokes provide excellent high
frequency noise suppression and, together with the temperature-controlled fan, low
acoustic noise.

Co n tr ol s ig n a l to the dimme r is v ia a s ta nd ar d D M X -512 socket at t he front panel, while
t h e d immed outlets an d three phase power entry are located on th e r ea r panel.

Feat u re s

• 12 x 2.4 KW dimming channels

• DMX-512 digital control protocol

• DMX terminating swit ch

• Su itable for both tourin g a nd permanen t in stallatio n s

• Soft turn o n characteristic

• Low acoustic/electrical noise

• Toroidal output chok es

• Circuit breaker protection of output devices

• Three mains phase indicator LEDs

• Built in test facilities

• Dimmer c urve set for linear r elationship between the con trol input and output power

• Compensates for fluctuations in the mains supply voltage, and filters superimposed

mains con trol tone s, ens uring a c on stan t light ou tpu t and inc re ased lamp life

• Rack mounted (3 rack units)

• Microprocesso r control

• Temperature-controlled cooling fan

• Temperature monitor and thermal cut-ou t

• Dimmer will hold last DMX value sh ould control data b e inte rrupted

• 50/60Hz operation

• CE and C-Tick approved

2.0 Equipment Description

2.1 Front panel layout

Refer to Fig 2.1 (below) for a description of the front panel controls.

1. Channel output sockets (rear panel): The twelve output sockets are each rat ed at

10 amps.

2. Channel circuit breakers: If a breaker trips during use ensure the fault has been

cleared before resetting.

3. Bank select switches: These switches select the DMX start bank and the Test

functions.

4. DMX IN LED: A red LED indicates the presence of DMX signals. If there is no

DM X s ig na l, t he LE D w ill fla sh a t a r a t e of a p p r o xima t e ly 2 s e co n d s o n - 2 s ec o nd s
off.

5. STATUS LED: A red LED flashes in the presence of a fault. In normal operation

this L ED shou ld be o ff.

6. PHASE LEDs: Three blue LEDs (one for each phase) indicate that t he three phase

mains supply is available.
