Description
GE TJL436300
Technical Specifications
- Manufacturer: General Electric.
- Part Number: TJL436300.
- Type: Dry-Type Control Transformer.
- VA Rating: Specific to model (typically 50VA – 500VA range).
Functional Features
- Voltage Isolation: Provides galvanic isolation between primary power and control circuits.
- Regulation: Tight voltage regulation under varying control loads.
- Thermal Protection: Internal thermal fuses or Class B/F insulation.
Application Scenarios
Machine control panels, PLC power supplies, relay logic circuits, and solenoid valve power.
Performance Parameters
- Primary Voltage: Typically 480VAC or 600VAC.
- Secondary Voltage: 120VAC, 24VAC, or 24VDC (with rectifier).
- Impedance: Low impedance to maintain voltage during inrush currents.
Material Composition
Silicon steel laminations for low core loss, copper windings, and epoxy-encapsulated or open ventilated housing.
Structural Characteristics
Compact rectangular or square profile. Features screw terminals or quick-connect tabs for primary and secondary wiring.
Working Principle
Operates on electromagnetic induction. AC current in the primary winding creates a magnetic flux in the core, inducing a proportional voltage in the secondary winding.
Installation Requirements
Mount vertically to ensure proper cooling. Fuse both primary and secondary sides appropriately. Ground the core and enclosure.
Usage Precautions
Do not exceed VA rating. Ensure secondary is not short-circuited. Check terminal tightness annually.
