Autotransformer

Hello Guys!

I've decided to buy an 500 VA single phase isolation transformer for my printing machines, electrical discharge machines, and automatic plug-in machines,. Here are features of transformer:

1. Cooling Mode: Natural or air cooling
2. Insulation Resistance: ≥50 MΩ
3. Electrical Strength: 2000V AC/1 min
4. Noise: ≤35dB (1 meter)
5. Insulation Grade: Grade B (130℃), Grade F (155℃), Grade H (180℃)
6. Overload Capacity: Allow more than 1.2 times rated load to work for up to 1 hour
7. Induced Overvoltage Withstand Test: 125Hz/800V/min
8. Impedance Voltage: About 6%
9. Total Losses: 10%
10. Certification: CE, ISO
11. Temperature: -15℃~+45℃
12. Enclosure Protection Grade: IP20
13. Warranty: 12 months

I've a question to engineers that is it suitable for machines or I should upgrade it with step-up transformer or step down transformer?
