Description
The High Risetime Dimmer Module is designed for use in Sensor®+ Dimming Series modular rack enclosures. Sensor High Risetime modules provide the highest risetime to reduce fixture hum and also support Advanced Features dimmer circuit feedback in AF-capable Sensor+ Racks and Portable Packs. The high-density, dimmer modules feature modular installation and removal, fully magnetic circuit breakers and high risetime toroidal filters. D20DHR modules dim accoustically sensitive loads without sacrificing dimmer density or efficiency.
APPLICATIONS • Incandescent lighting • Low voltage lighting • Quartz lighting • Neon lighting • Cold Cathode lighting • 2-wire Fluorescent ballast • 4-wire Fluorescent ballast
FEATURES • Voltage, current, and temperature sensors in each dimmer • D20HR modules are single density • D20DHR modules are dual density • D50HR modules are half density • Dual back-to-back SCRs for each circuit • 800μS or 1000μS risetime toroidal filters • High-density modular assembly • Die-cast aluminum chassis • Fully magnetic circuit breakers
GENERAL • 100,000A Short Circuit Current Rating (SCCR) • UL and cUL LISTED

SPECIFICATIONS:
GENERAL • UL and cUL Listed for continuous duty at 100% of rated load • D20HR – 2.4kW • D20DHR – 2.4kW • D50HR – 6.0kW
PHYSICAL • Modular plug-in assemblies • Cast aluminum chassis, finished with textured epoxy paint • Keyed to prevent insertion in inappropriately rated rack positions
CIRCUIT BREAKERS • Fully magnetic to eliminate nuisance tripping • 20x inrush current rating • 125%, 10-120 seconds, must-trip rating • Rated for 100% switching duty applications
RATINGS • 100,000A Short Circuit Current Rating (SCCR) • Modules withstand hot-patching of cold loads up to full rating
Power Device • Sealed, patented assembly • Field replaceable with screwdriver • Two back-to-back SCRs per circuit • One control LED and one output LED per circuit • Integral bonded heatsink • Integral temperature sensor • Built-in voltage and current sensors
FILTERING • High quality 800μS or 1000μS risetime toroidal filters* * Risetime measured at full load, at worst case firing angle (90 degrees), from 10-90% of output wave form
DIMMER RANGE • Incandescent, low voltage dimming range 100-0% • Dimming range of 2 and 4-wire fluorescent ballast is dependent on lamp ballast combination. Contact ETC for range verification • Sizing of Neon transformer used in dimming applications should be 1.5x greater than size used in non-dimming application
Advanced Features** • Advanced Features error messages: - Load dropped below recorded value - Load increased over recorded value - DC on dimmer output - SCR failed on/off - Circuit breaker tripped - Dimmer module removed - Dimmer load absent
** All HR modules support ETC’s Advanced Features (AF) dimmer specific load reporting features when used in AF-equipped racks or packs
