 +/- 24vdc to 115vac
 600VA and 900VA
These heavy-duty XINv Series dc to ac inverters are housed in a 2U rack-mountable enclosure. XINv PWM inverters feature a transformer isolated sine wave output. They are designed for all applications requiring continuous pure sine wave power. The models on this page produce 115 volts ac (or 110V or 120V) from +/-24 volts dc.

Typical XINv series applications
Applications include all waveshape sensitive equipment such as telecommunications systems, industrial, measurement and other mission-critical, harmonic-sensitive electronics. They are also ideal for use in facilities with 24 vdc rectifier/battery power plants, where the inverter can be used to provide the function of a double-conversion on-line UPS.

Key XINv series benefits
XINv uses high-performance microprocessor and unipolar pulse-width-modulated (PWM) power conversion circuits for high efficiency and low input dc ripple currents. They also feature high dc to ac power conversion efficiency, pure sine wave output and long MTBF. XINv also provides precision automatic voltage regulation with 115vac +/-3% and less than 5% THD. XINv’s 2U high construction with optional wall or rack-mounting kits provides maximum flexibility for telecom and industrial users. XINv offers a hardwire terminal block battery connection with a dc circuit breaker for external 24vdc battery banks.

How the XINv series works
 A rugged, high-performance microprocessor and unipolar pulse-width-modulated (PWM) power conversion circuit takes the dc input and converts it into a pure sine wave. The circuitry automatically adjusts the duty cycle of the output for all loads and inputs. XINv delivers a stable 60Hz +/-0.5% frequency. A dc circuit breaker protects all dc circuits, and an overload shutdown feature protects the inverter from overload. If the input dc voltage drops below 21 vdc, a DB9 connector in the rear of the inverter sends signals for inverter output failure and low dc input voltage. A comprehensive array of output current, battery charge levels, and status LED indicators are provided for visual assessment of inverter status. A DB-9 port is provided for communication using RS-232 or dry relay contact signals.
