The universal switching power supply works with 100 to 240 VAC, 50/60 Hz. 2.
Description & Operation • Each channel delivers 100 watts of power into a 4 or 8Ω load (constant power). º Average load impedance is estimated, then used to set the limiter to confine the maximum average power to 100 watts. • Universal voltage, power-factor-corrected power supply (see figure on data sheet). º Switch-mode power supply operates 100 to 240 VAC, 50 Hz or 60 Hz. º Under- and over-voltage protection with inrush current management. º The power supply features an IEC appliance inlet.
• Individual FAULT FLAG ports are provided for each channel. OUTPUTS MA 4 COMMERCIAL AUDIO MADE IN U.S.A.

A detected fault is re-tested every 104seconds. 3 LOAD LOAD LOAD OFF.
Advanced Applications Remote Turn-on To operate an amplifier channel in low power standby with remote turn-on, set its rear panel switch to SLAVE. External +5 volts connected to the FAULT FLAG holds the amplifier in standby. Floating the FAULT FLAG or connecting it to ground turns the channel on. MADE IN U.S.A. RANE CORP.
