Leviton IAC20-115 i Series e, Dual Constant Module, 120-Volt, 1.8-Kilowatt

SPECIFICATIONS

• The dimmer module is designed for superior reliability in the most demanding of operating conditions
• Each dimmer module also monitors its temperature and reports this information to the control module
• Each dimmer module has a dedicated optically isolated control signal line from the control module
• Failure of one module cannot affect the operation of any other dimmer module

MECHANICAL

• All dimmers are housed in removable modules made of die-cast aluminum. Each module contains one or two circuit breakers, a solid-state SCR switching device (SSR), an interface PCB, and two filter chokes. The face of the module has a handle, the circuit breaker switches, air vents, and labeled LEDs for local feedback. The left side of the module has a wide section of spring steel to insure a proper fit for each module in the rack. All electrical contacts feature selfaligning floating connectors to insure precise alignment of all connections. Modules are keyed so that a module of higher ampacity cannot be inserted into a slot that is wired for a lower ampacity dimmer. All dimmer modules can be inserted and removed without the use of any tools.

ELECTRICAL

• The i Series® e dimmer module is designed to operate on voltages ranging from 90-135VAC (120V Nominal) or 187-265VAC (230V nominal) at 47-63 Hz. The dimmer module electronics’ firing signal is optically isolated to 4,000 Volts from the power semiconductors.
• The module can also maintain proper output voltage regulation within +/- 1 Volt over the line voltage range
• When a dimmer is set as a non-dim, it passes an unregulated sine wave
• Each dimmer tracks operating conditions and provides feedback to the Hand Held Terminal, which transmits the information to the user interfaces and/ or the LEDs on the face of the dimmer module. Realtime feedback information includes the following data: Overtemperature Warning, Overtemperature Shutdown.
• Modules are available in standard (500µs) rise time. Oscillographic evidence of rise time data is available upon request
• Airflow modules are required in unused slots in order to maintain proper rack ventilation
• 120V units are UL listed and cUL listed (for Canadian applications)

FEATURES

• Power regulation gives smooth consistent power output despite fluctuations in line power input
• LEDs on each module offer immediate local feedback at the rack
• Individual module overtemp warning and shutdown feature
• Control signal is optically isolated to 2,000 Volts
• Standard 500 microsecond and high performance 800 microsecond rise time models available
• Rugged mechanical design for reliability
• “Floating” load and line connectors allow for smooth insertion and removal of the module and ensures the integrity of all power and control contacts
• User serviceable components
• 120V Units UL Listed and cUL Listed
