There is also provided on the panel a step-down transformer 3 which is the same as that shown at 3 in the patent and there are control relays 86 and 87 corresponding to relays 86 and 87 of Figure 6 of the patent, but with relay 87 having an additional pair of cooperating contacts 90...
Control Wiring Modifications:All DCS800-EP panels use a control transformer to step the incoming line voltage down to 115V. This control voltage is used to power the drive module fans as well as the starter used to control the motor blower. These various fans are all running anytime line v...
A welder apparatus has many welder assemblies. Each of welder assemblies is formed of a weld control transformer (WCT) to which a welding gun is attached, and a weld control unit (WCU) integrally but detachably connected to the WCT. The feature of the detachable connection between the WCT ...

WIRING DIAGRAM:ORDERING INFORMATION:1.AC Current Control Without Latching:The output relay is energized when the current (peak current on AC) over-shoots the level selected on the potentiometer. It de-energizes when the current falls below the normal current by 5 to 50% or when input power ...
This type of event can be caused by lightning strikes coupled through a power transformer secondary, or by localized power faults due to machine failures. Test methods for this type of hazard are documented in IEC61000-4-5. External protection diodes are typically added to provide a safe path...
