Provides isolated voltage conversion for stable operation and protection of connected devices.

## Long description

Step-down voltage transformer KEMOT URZ3421 230→115 Vac 500 VA converts mains 230 V AC to 115 V AC with a rated capacity of 500 VA. The unit provides isolated voltage conversion suitable for devices designed for 115 V operation when only 230 V supply is available. It is intended for stable powering of small appliances, electronic equipment and test setups where reliable step-down transformation and galvanic isolation are required.
Advantages
The transformer delivers a stable 115 Vac output under its rated load and includes galvanic isolation between primary and secondary windings to reduce interference and improve safety. Compact construction with a clearly specified VA rating makes it easy to select for matching loads. The device is passive and does not require additional electronics to operate, offering simple, low-maintenance service life when used within specified limits.
Suitable for
 Powering small appliances rated for 115 V from a 230 V mains
 Supplying electronic lab equipment and test instruments
 Use in workshops and hobbyist setups for conversion of mains voltage
 Temporary or permanent installations where isolation and reliable step-down are needed
Key specifications
 Input voltage: 230 Vac
 Output voltage: 115 Vac
 Rated capacity: 500 VA
 Type: step-down isolation transformer
 Typical use: powering 115 V appliances and equipment from 230 V supply
How to use
Install the KEMOT URZ3421 in a dry, ventilated location and secure it according to mounting provisions. Connect the primary side to the 230 Vac supply and the secondary side to the 115 Vac load, observing correct polarity and grounding practices if required by the installation. Do not exceed the rated 500 VA load; observe the transformer's temperature during prolonged use and allow adequate cooling space. For permanent installations, follow local electrical codes and, if necessary, consult a qualified electrician for wiring and earthing.
Usage recommendations
Use the transformer within its rated capacity and avoid high inrush currents from inductive loads exceeding the VA rating. For sensitive electronic equipment, allow the transformer to stabilize after connection and verify output voltage under expected load conditions. Ensure proper grounding and maintain clearance for ventilation to prolong service life.
