300 Watt Step Down Transformer – Use 110-120 Volts Appliances in Mexico AJSD-300


ACUPWR’s AJSD-300 model is a grounded step down transformer that converts voltage from the 127-130 standard used in Mexico to 110-120 volts, allowing you to use your USA and Canada appliances in Mexico, Brazil, Bonaire, Curacao, and Suriname.

Please note: The AJSD-300 is for using American and Canadian products in 127-130 volt countries only (Mexico, Brazil, Bonaire, et al.). ACUPWR manufactures other step down voltage transformers/converters (with similar wattage loads) that can be used for other countries and regions, such as the AD series (220-240 volts down to 110-120), the AJD series (110-120 volts down to 100 volts, for use in Japan), and the AUD series combination step up/step down model (110-120 volts up to 220-240 and down from 220-240 volts to 110-120).

  • Made for home, commercial, and industrial use
  • Converts voltage from 127-130 volts to 110-120 volts
  • Allows appliances running on 110-120 volts (USA and Canada) to be used in Mexico, Brazil, Bonaire, Curacao, and Suriname
  • Compatible appliances include stereo systems, electronic gaming devices, and paint sprayers and much more (please refer to our transformer guide)
  • ACUPWR products are trusted by military, NASA, and government agencies worldwide

  • Bench tested for quality assurance and years of reliability

This model is rated for 300-watt loads and suitable for home, commercial, and industrial applications. Compatible appliances include stereo systems, electronic gaming devices, and paint sprayers and much more (please refer to our transformer guide). The AJSD-300 comes with a grounded Type B plug and a NEMA 5-15R (input) recepticle for up to 15 amps maximum power. Although Mexico’s 127-130 volts are only slightly higher than the 110-120 volts used in the USA and Canada, the difference is particularly noticeable when using electronic devices.

As with all ACUPWR products, the AJSD-300 is proudly manufactured in the USA using the best materials available. This includes copper wiring that allows the AJSD-300 to operate under heavy duress, and in the most heavy-duty situations. Unlike less expensive, foreign-made products using aluminum wiring, our products are designed to last for decades. Each unit is hand assembled in our factory and bench-tested at a full-load (the maximum stated wattage) to ensure years of dependability. Among the AJSD-300’s features is thermal protection (CTOC); the unit will turn off when overheated.

ACUPWR stands by its products by providing a lifetime warranty and insurance coverage up to $10,000. We count military and government agencies, including NASA’s Goddard Space Flight Center, among our customers for good reason: ACUPWR products are the best-made, most dependable, and most long-lasting transformers available.

When considering which model ACUPWR transformer/voltage converter is best for your needs, keep in mind that our products are safe for continuous power at 120 percent beyond the stated wattage, unlike other products that adhere to an industry standard of 2-3 times higher than the appliance’s stated wattage. So, for example, an appliance rated for 300 watts of consumption would, according to the industry standard, require a 900-watt transformer. With an ACUPWR transformer, you can safely use your 300-watt appliance with a 300-watt transformer/converter; our products, remember, can handle 120-percent beyond their stated wattage handling ability.

ACUPWR recommends that you purchase our Global Surge Protector to protect your appliances from voltage spikes. Additionally, our Global Surge Protector allows you to plug in up to 6 appliances using any plug type, thus ensuring its use anywhere in the world. We also highly recommend our voltage stabilizers/line conditioners, in countries where the line voltage is particularly unstable.
