Metro Inverter 1500W

The ODS-1500 is a single-phase sinusoidal DC/AC inverter rated 1200–1500 W with selectable 120 or 230 Vac output. Its wide DC input range from 12 to 110 Vdc covers battery bus voltages from 12 V automotive to 110 V railway strings. A railway version with tropicalized circuits and EN50155 compliance is available for all models.

Internal forced-air cooling and efficiency up to 91%. Maximum average power and peak current protection, input under-voltage disable, RS232 control via PAM Tool, and isolated relay alarm contacts ensure robust integration. Accessory: ACI-3000 inrush current limiter.
