The Hercules voltage and frequency converter is fully universal!  Will precisely convert worldwide mains voltage or frequency to what you need, with great accuracy, assuring rock-solid performance.  The output receptacle is universal.

Hercules will power devices up to 200 watts (instantaneous power over 300 watts available--please contact us).  Voltage AND frequency can be selected as needed, either 115V or 230V AC, at 50Hz or 60Hz, from anywhere in the world, regardless of frequency or voltage available locally. You can select the desired plug style to match your local outlet at checkout.   Output receptacle style accommodates most worldwide standards.  NOTE:  Cannot be used for powering 160-watt wine coolers.  Use Mercury 500 for this application.

Why do you need a Hercules frequency converter? Devices with motors that turn or vibrate are very dependent on power line (mains) frequency to do their job properly and at the right speed.  Hercules has been used to power devices from vintage tube-based audio equipment to industrial manufacturing and rework gear.

Hercules also includes a remote programming port, if you need it.
