FM-10S 10 kW Solid State FM Transmitter Frequently Asked Questions
MODEL FM-10S
Power Range: 5kW to 10kW
AC Voltage Requirements: 196 to 252 VAC, 50/60 Hz, 3 phase, Closed
Delta or WYE (3 or 4 wire)
340 to 435 VAC, 50/60 Hz,
3 phase, 4 wire, WYE only
Disconnect Size: 100 Amp fused disconnect recommended
Actual amperage draw at: 10kW - 50A, average, actual determined by
line voltage, carrier frequency, etc.
AC wire size: 1 AWG copper, THHN or equivalent
Power Consumption: 17.3kW at 10kW RF output
Cooling Air requirements: 2700 CFM
Air Outlet (PA exhaust) size: Top of Cabinet (27" x 45")
Heat dissipation: 7.3kW (24,915 BTU/hr) at 10kW RF output
To determine Air Conditioner
size for closed system: one BTU/hr = 0.293 watt
one watt = 3.413 BTU/hr
12,000 BTU/hr = 1 ton of A/C
eg, at 7.3kW dissipated, a 2.1 ton A/C unit would
be needed (7,300 x 3.413 = 24,915/12,000 = 2.1)
Output connection size: 3 1/8" EIA female (1 5/8" optional)
Weight: 660 lbs. standard unpacked
