Sensor3 CE Rack Specifications
All of the rack specifications apply to all of the ESR3 series of
racks unless otherwise noted.
General
Racks available in four sizes
• ESR3-12: 12 modules, 24 dimmers maximum
• ESR3-24: 24 modules, 48 dimmers maximum
• ESR3-36: 36 modules, 72 dimmers maximum
• ESR3-48: 48 modules, 96 dimmers maximum
Dual density (two dimmers per module) and single density
dimmer modules available
Envir onmental
Operating temperature: 0-40C / 32-104F
Dimmer room HVAC systems must at all times maintain the
specified ambient temperature at the dimmer rack. Dimming
systems operating within 10 degrees C of the upper or lower
temperature limits must strictly follow installation and
operation guidelines to operate reliably.
Relative humidity: 30-90% non-condensing
Altitude: Below 2000 metres.
Mechanical
Rugged 16-gauge steel construction
Fine-textured, scratch-resistant, epoxy paint
ESR3-12 uses wall mount installation
ESR3-24 can be wall or pedestal mounted
ESR3-36 and ESR3-48 are floor mounted
Top and bottom cabling access through removable panels
Screwdriver required for module removal or installation
Keyed module slots prevent insertion of inappropriate module
types
Front access to all wiring and terminations
Full height locking door
Electrostatic air filter easily removed from door for periodic
cleaning
High efficiency cooling system with airflow sensor
High visibility LED status beacon
Elect rical
ESR3 racks accept:
• Single phase 230V AC (3-wire)
• ESR3-36: restricted to a max.600A across all circuits
• ESR3-48: restricted to a max. 800A across all circuits
Three phase 230/415 V AC (3-wire)
Line feed frequencies from 47-63Hz
Maximum current ratings:
• ESR3-12 – 200 amps per phase (3 phase max.)
• ESR3-24 – 400 amps per phase (3 phase max.)
• ESR3-36 – 600 amps per phase (3 phase max.)
• ESR3-48 – 800 amps per phase (3 phase max.)
These are absolute maximum current ratings. You may use
less dependent on the type and number of dimmer modules.
