750 VA Inverter
750VA, 110V DC/415V AC Natural Cooled Inverter For Water Raising Pump Load In Train set Coaches
Specification No. ICF/ELEC/172
Description:
- 750 VA inverter converts 110 V DC (from coach battery) into regulated 415 V, 3-phase pure sine-wave AC output.
- Specifically designed to power water raising pumps in trainset coaches.
- DSP-based, high-frequency, double conversion design with soft start feature for efficiency and reliability.
- Naturally cooled and engineered to withstand vibration, shock, humidity, and dust in railway environments.
- Developed as per ICF Specification No. ICF/ELEC/172, ensuring safety, standardization, and compatibility with trainset systems.
