Reliability

7/8

From initial design to product build, we ensure that every power source we release to a customer meets our standards for reliability and efficiency.

Power Section designed around high speed switching modules

Lincoln manufactures its own integrated modules, which allows us to optimize each module for reliability

and performance.

Designed to withstand extreme environmental conditions

All PC boards are trayed and potted.

The transformers and chokes go through a double dipped varnish impregnation process.

Harness connectors are made with locking pins and sealed with electrical grease.

Designed with

Fan As Needed (FANTM) Circuitry

This reduces the amount of debris that gets drawn into the machine by turning the fan off when it is not needed.

The fan turns on before components get too hot, thus increasing life expectancy of the electronics.

Reduces the power used during machine idle.

All electrical components are derated for added reliability

All electrical components are designed to operate at voltages lower than their rated voltages and temperatures below their rated temperatures.

Designed for stable operation

Patented dual current transformers prevent current imbalance.

Active balancing technology is utilized for keeping the voltages balanced under all conditions.

Control system utilizes common PC boards and software

Able to accommodate feature enhancements and optimizations from other products for longer life of the inverter.

Designed for protection if a fault occurs

Thermal protection, misconnection protection, secondary over-current protection, and primary over-current protection are all standard in inverter machines.
