Telecom 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.

• Output: 1200–1500 W, 120 or 230 Vac single-phase pure sine wave, selectable 50/60 Hz, adjustable output voltage


• Input: 6 voltage versions — 12, 24, 36, 48, 72, 110 Vdc (operating range 10.8–138 V)


• Control & monitoring: RS232 remote control; alarm by isolated relay contacts; remote off opto-coupled; remote inhibit


• Isolation: 3000 Vrms; efficiency up to 91%; forced air cooling

In telecom and data infrastructure applications, this inverter provides regulated AC power for network equipment, UPS bypass loads, and AC-powered instruments in 48 Vdc or 24 Vdc telecom power environments. The pure sine wave output ensures compatibility with switch-mode power supplies used in routers, servers, and base station equipment. Its low harmonic distortion (THD <3%) prevents interference with sensitive telecom signal processing hardware.
