Output protection—Apex generators sense and employ several parameters for protection
Reflected power limit 20% of maximum forward power for units rated for less
than 5500 W. 1000 W for 5500 W units. (PIN position 2
defines the maximum forward power rating for the unit.)
Dissipation limit Maximum PA dissipation—non-latching alarm LED
Low/high line bus Bus voltage outside spec window—latching alarm LED
Over-temperature Over-temp condition—latching alarm LED preceded by
non-fault warning (user setting).
Output power range All generators except the HALO will allow setpoints
between 1% and 100% of full scale. The exception is the
HALO 1.5k generator depicted by “L” in position 2 of the
PIN number. This allows setpoints from 5 watts to 1500
watts.
Output power regulation accuracy
Into 50
Ω non-reactive load
• ± 1% of setpoint or ± 0.1% of full-rated output,
whichever is greater (all PIN position 2 options but K
and L)
•
≤ ±1% of setpoint or 0.25 W, whichever is greater
(PIN position 2, option K & L)
Into 3:1 VSWR non-
reactive load ± 3% of setpoint (load power regulation), over all load
phase angles, or ± 0.25% of full-rated output, which ever is
greater
Load regulation as a function
of line regulation Less than 0.1% change in output power for 10% change in
ac line voltage
Load regulation as a function of temperature—(performance in accordance with the output
power regulation accuracy)
