AC & DC UPS with 30A Rectifier for Integrated Power Supply
The DAC300-G2 AC & DC UPS combines a 24V DC rectifier and charging system with a 230V AC sine wave power output, providing integrated power management for electrical and electronic equipment.
The DAC300-G2 is an AC and DC Uninterruptible Power Supply (UPS) incorporating a 30A rectifier, DC charging functionality and an AC inverter output within a 19-inch rack-mount enclosure. It operates with a 230VAC single-phase input and provides a nominal 24VDC output alongside a 230VAC, 50Hz sine wave AC supply.
Designed for applications requiring both AC and DC power functions, the system includes adjustable float charging, voltage regulation, monitoring indicators and integrated protection functions. Its microprocessor-based temperature controller and remote indication signals also support the monitoring of associated operating conditions.
SYSTEM FEATURES
Integrated AC and DC Power Management
The DAC300-G2 provides combined AC output, DC charging, regulation and system indication functions within one rack-mount power supply system.
30A Rectifier and Charger
The integrated charging system provides up to 30A DC charging current, with adjustable linear constant-voltage float charging at a specified 27.6VDC setting.
Automatic Voltage Regulation
Built-in AVR with MOV surge protection and EMI/RFI noise suppression forms part of the system's documented power conditioning and protection functions.
Power and Battery Protection
Protection functions include output overcurrent and short-circuit protection, DC high-voltage protection, battery low-voltage detection and automatic battery cut-off.
Temperature Monitoring
A microprocessor-based temperature controller with one sensor provides adjustable temperature monitoring settings and supports associated ventilation control indications.
System Status Indication
LED indicators and remote indication signals provide information about mains supply, charging, AC and DC output, charger faults, low battery and temperature-related operating conditions.
