TECHNICALSPECIFICATIONS

A] Aluminum rack 4 x 3 profile sturdy flat panel (table top) system, carrying various high voltage components housed in plastic enclosures (panel) to minimize shock possibility.

 Input 3 phase DOL Starter panel Module 1

• 4 pole MCB of 415 V/2A
• DOL9A Contactor with 230V / 50Hz / 11VACOIL
• Bimetallic thermal O/L relay with range 1.4A – 2.3A

Integrated AC (1 phase) measurement panel Module 20F– 2 Nos.

• Consist of 2 nos of (48 x 96 mm) Digital meters for Measures V, I, PF (0.2 lag unity 0.2 lead), Hz. Hence separate analog watt meters are not needed.
