DigiPower 4x150T_D

• 230 VAC and 24 VDC power supply with automatic switching
• Automatic standby mode (selectable via DIP switch)
• Control LEDs for all signal and operating contitions
• Monitoring contacts for AC and DC supply and power stage status
• 4 channels in 1U / 19" housing
• 4x150W, 100V direct outputs
• Balanced inputs
• Installation depth 322 mm
• All connections with plug-in terminals
• Protection circuits: automatic shutdown in case of overtemperature, overload and short circuit of the speaker lines
• 2 temperature controlled fans

Four-channel digital power amplifier with 4x150W nominal power for professional, electro-acoustic voice alarm systems.The electronic protection circuits ensure the necessary safety of the amplifier. In case of a power failure the amplifier automatically switches to emergency power mode (external battery 24V). A very reliable electronic design guarantees uncompromising transmission quality and long-term, trouble-free operation. Digital power amplifiers with a direct output, without a transformer, off er high efficiency with low weight, smaller size and comparatively less waste heat.

•  Digital power amplifiers with 100V direct output
•  Level control for each channel (step switch for exact reproducibility)
•  Display of all operating states by LEDs
•  Serial RS485 interface (on/off per channel, individual error messages)
•  Temperature-depending fan control
•  Monitoring contacts for AC and DC supply
•  Potentional free collective fault message
•  Only 322 mm installation depth
