Key Features
220 V to 110 V Step-Down Conversion
The ST-50 steps down the AC supply voltage for compatible equipment. Check the input voltage range printed on the transformer against your supply before connecting it.
50 W Rating for Low-Power Loads
Check the device’s input rating and any start-up demand against the transformer’s label and instructions. Ask for help with sizing if the device is rated in VA or amps, or if its demand is close to the transformer’s rating.
Frequency and Plug Compatibility
The transformer changes voltage while the supply frequency stays the same. Confirm that your device supports the supply frequency and that its plug and earthing requirements match the transformer.

What Can I Connect to the Astram ST-50?

Astram ST-50 FAQs
Do I need this transformer for a charger marked 100–240 V?
A charger rated for 100–240 V generally needs only a suitable plug or adapter when the supply voltage and frequency both fall within its stated input range. Check the charger label first.
Can the ST-50 power a device rated for 60 Hz only?
On a 50 Hz supply, the ST-50 output remains at 50 Hz. Ask the device manufacturer whether the equipment supports 50 Hz before connecting it.
Can I use it with a device labelled 120 V?
Check the device’s permitted voltage range. Use the ST-50 only if the manufacturer confirms that 110 V is within that range and the frequency and load requirements also match.
