Frequently Asked Questions
Q1: What is the benefit of a True Sine Wave output? A1: True Sine Wave output (T.H.D < 3%) ensures the highest quality power, making it compatible with sensitive electronic equipment and reducing electrical noise and heat.
Q2: How fast does the inverter switch between DC and AC bypass? A2: The system features an ultra-fast automatic switch function with a transfer time of less than 5ms (DC to AC) and less than 8ms for inverter to bypass transitions.
Q3: Can I monitor the system remotely? A3: Yes, the unit comes standard with RS232 and RS485 ports, and supports an optional SNMP communication port for full remote network monitoring.
Q4: What kind of information does the LCD display show? A4: The large digital LCD displays critical data including input/output voltage, frequency, output current, internal temperature, and capacity rates.
Q5: Is this inverter suitable for server room installations? A5: Absolutely. It is designed with a standard 19-inch rack-mount case, making it ideal for IT infrastructure and server rack environments.
Q6: What built-in protections are included? A6: The system includes integrated protection against short circuits, overloads, battery over/under voltage, over current, and over temperature.
