Our 500VA single phase control transformer provides a stable 24V
output from a 220V input, purpose designed for lighting control
circuits, solenoid valves, signal lamps, and auxiliary control
loads in industrial control cabinets. This JBK series control
transformer delivers safe extra low voltage power that meets the
needs of machine builders and panel manufacturers while eliminating
the risk in frequently touched control devices. The high
permeability silicon steel core and high purity copper windings
ensure ≥90% working efficiency, low temperature rise, and quiet
operation below 50dB, while the dry type air cooled enclosure
allows compact installation inside control cabinets. With its
reinforced terminals, convenient wiring design, and ±2% output
precision, this transformer provides dependable 24V power for the
most demanding production environments.
Key Features- Safe 24V Extra Low Voltage: Steps 220V mains down to 24V for control lamps, solenoid coils,
sensors, and auxiliary circuits, significantly improving operator
safety in industrial control panels.
- Compact Cabinet Mounting: Small footprint JBK enclosure with reinforced terminals and
convenient wiring design fits neatly into standard electrical
control cabinets and terminal boxes.
- High Efficiency Low Loss: Premium silicon steel core with high magnetic flux and minimal
energy loss delivers ≥90% working efficiency and a low temperature
rise of less than 80K even under continuous full load.
- Robust Insulation System: Class F insulation and ≥5MΩ insulation resistance withstand 3500V
dielectric strength tests, ensuring long winding life and safe
isolation of the control circuit.
- Precision Voltage Output: ±2% output accuracy keeps 24V loads within specification despite
input voltage variation, protecting sensitive sensors and
electronic timers from overvoltage damage.
- Quiet Reliable Operation: Noise level below 50dB and oil free dry type construction require
no maintenance and cause no interference in sound sensitive
production areas.

ApplicationsThis 500VA control transformer is the standard 24V power source for
industrial control cabinets, machine tool electrical panels,
conveyor control systems, packaging machinery, and HVAC control
panels. It is also widely used to power LED machine lighting,
solenoid operated valves, proximity sensors, and programmable logic
controller auxiliary circuits in factories worldwide. Custom output
voltages including 12V, 36V, and 48V, together with OEM terminal
configurations and branded enclosures, are available to match the
exact electrical drawings of original equipment manufacturers.
Packaging & Quality AssuranceStandard export packaging uses a shockproof carton, with a
reference packing size of 15X15X15CM and a gross weight of
approximately 8KG per unit. Every transformer is manufactured in
our CE, ISO9001, and UL certified factory and passes complete pre
shipment testing, including insulation resistance measurement,
voltage ratio verification, and no load running checks. We provide
OEM/ODM customization, a minimum order quantity of one unit, 3 to 7
working days delivery for standard models, and lifetime technical
guidance for installation and troubleshooting.
