Protection

Over/Under Voltage:
± 10% from specified supply voltage amplifier is forced to Standby
Over Current:
Breaker protection on both main power and low voltage supplies
Over Temperature:
Separate Output transistor, heat sink, and transformer temperature monitoring and protection

Physical Characteristics

Chassis:
Black powder-coat chassis with all aluminum construction; designed for stand-alone or rack-mounted operation. The amplifier occupies seven EIA 19-inch-wide rack units
Weight: 160 lbs (72.5 kg)
AC Power: Three-phase, 208 VAC ±10%, 47-60 Hz, 30A AC service (400 VAC ±10%, 15A version available). A toggle switch circuit breaker opens all legs of the AC mains on excess current demand.
Operating Temperature:
10°C to 50°C (50°F to 122°F), maximum output Power de-rated above 30°C (86°F).
Humidity: 70% or less, non-condensing
Cooling: Forced air-cooling from front to back through removable filters via four 100 ft3/min. fans. No space is required between rackmounted amplifiers. Air filters are removable from the rear via one fastener per side and may be eliminated if cabinet filtration is provided.
Dimensions (HxWxD): 12.25” x 19” x 22.8” (31.1 cm x 48.3 cm x 57.8 cm)
