SMC LET-400 – Primary Injection Test equipment up to 2,500A

• Primary Injection Test equipment up to 2,500A
• Permanent current up to 400A 1KVA in 4 Ranges
• Built-in digital ammeter 0.5% accuracy
• Built-in digital timer resolution 1 ms
• Thermal and shortcircuit protection

It allows to perform with sufficient power, all the primary current injections to test the proper function and wiring of all the elements that compose the protection and measuring section in a substation.

The regulation system is based on a continuously variable autotransformer (Variac) that supplies to a power transformer that delivers the high current outputs and isolates the main supply from the load.

• Permanent current up to 400A 1KVA in 4 Ranges.
• Thermal and shortcircuit protection.
