D 66 K3
Digital dimmer
Double circuit breakers (1P+N) ensure electrical safety in case of
short-circuits and electrical overload, cutting both phase and neu-
tral conductors. Double fan forced cooling system provides uniform
cooling, adequate with dimmer’s power.
This dimmer has been designed with robust power components,
paying special attention to internal electrical wiring which has been
reinforced to protect the dimmer from voltage drops, noise and
unnecessary warming.
Electronic components are controlled by a microprocessor to
maintain a precise regulation, even in case of frequency variations,
voltage drops and noise in the network.
D 66 K3 is very easy to use, thanks to its useful LCD display and
quick access to the main functions of the menu.
PROTECTIONS
- Double thermal circuit breaker (1P+N) for
electrical safety in case of short-circuits and
electrical overload, cutting both phase and neutral
conductors.
- Double fan forced cooling system (2 fans of 120
mm), with automatic operating mode to reduce
temperature to pre xed value.
- Slow start with starting  ange of 4 seconds to
prevent from current peaks.
- Power frequency auto-adjustment between 47
and 63 Hz (according to power input requirements)
to do not affect the response curve. Associated with
the Zero Crossing Detector (ZCD) for stable output
levels.
- Synchronization with microprocessor marks
zero crossing points, detects and  lters spurious
frequencies produced in the power supply.
- Programmable protection: con guration of each
output with a maximum level to avoid sudden level
variations that can affect load (a 95% output level
is efficient and almost undetectable).
- 0-100% duty cycle: internal  lter and detection
circuitry to eliminate parasite noise and use the full
cycle during zero crossing process.
