Confirm the site and equipment requirements
Hz means cycles per second of alternating current. Send the project location, utility frequency and main equipment nameplates. Country information is a starting point: imported equipment, isolated supplies and special systems may differ. Confirm the actual site and equipment requirements.
Changing frequency involves more than a setting
A conventional four-pole synchronous alternator runs at 1500 rpm for 50 Hz and 1800 rpm for 60 Hz; other designs can differ. A frequency change requires review of the engine, alternator, voltage regulation, controls and ratings. A catalogue 50 Hz model is not a confirmed 60 Hz configuration. Do not adjust speed and connect loads without an approved configuration.
Check motors and electronic equipment separately
Motor speed depends on frequency as well as pole count, slip and drive arrangement. Incorrect frequency or voltage can affect torque, heating and performance. Equipment labelled 50/60 Hz still has permitted voltage, current and operating conditions. Variable-frequency drives also have input supply requirements.
Compare products and prepare an inquiry
The product cards show existing published frequency specifications. For 60 Hz, specify target voltage, phases, power and a load list so availability and ratings can be confirmed. Do not reuse the 50 Hz power rating. Nameplate photos and the intended duty help clarify the configuration.
