EX ELECTRONIX EXPRESS Variable Transformer, 300 VAC Max, 0-130V Output, 3 Amp

Model: 16VA520T03   |    Mpn: SC-3M   |    Ean: 0857549003111   |    PartNumber: SC-3M   |   Asin: B006NGI8VS

This variable transformer is a great device for quality control testing, equipment testing on low and high voltage, control over heat, speed, and more. In order to purchase the right variable transformer, it is critical that you know the amp usage by your electronic device. It is always best to be conservative otherwise you risk destroying the variable transformer and it can be very dangerous. Most devices have a surge amperage (when first turned on) that is much higher than the device's operating amp rating. For example, if your device requires 3 amp, buy the variable transformer with up to 5 amp to account for the surge amperage. A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2.5amp. Note - Indoor use only. Do not operate in a condition that may cause electrocution and fire. Do not operate in a wet environment. Do not operate near flammable substance.

Features

  • Input: 120 volt AC, Output: 0~130 volt AC, 3 Amp Slow Blow Fuse
  • Max VA: 300VA, 3 Amp. Max (surge)
  • A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2.5amp
  • WARNING: Most devices have a surge amperage (when first turned on) that is much higher than the device's operating amp rating.
  • EXAMPLE: A motor with a 3 amp rating may have over 5 amp surge, and you will need a 5 amp variable transformer

Siemens MT0075A Industrial Power Transformer, Domestic, 240 X 480, 230 X 460, 220 X 440 Primary Volts 50/60Hz, 120/115/110 Secondary Volts, 75VA Rating

Model: MT0075A   |    Mpn: MT0075A   |    Ean: 0754554026701   |    PartNumber: MT0075A   |   Asin: B0052MY200

This Siemens MT0075A industrial power transformer has a 75 VA power rating, a voltage letter designation of A, and reduces 240 x 480, 230 x 460, or 220 x 440 V (primary voltage) to 120/115/110 V (secondary voltage). A silicon steel-laminated core and copper magnet wire increase transformer efficiency, which decreases the destabilizing effect of inrush current on secondary voltage. Epoxy-encapsulated transformer coils resist moisture, dust, and industrial contaminants, and built-in terminals and barriers resist breakage. Steel mounting brackets provide stable mounting and slotted mounting feet make installation easier. The thermal insulation class for this transformer is 105 degrees C with a 55 degree C (131 degrees F) temperature rise. This power transformer is Underwriters Laboratories (UL) listed and CSA International certified, and is suitable for use in transforming electrical power for machine tools and industrial control circuits.

Specifications Primary voltage 240 x 480 V, 230 x 460 V, 220 x 440 V Secondary voltage 120/115/110 V Voltage letter A Power rating 75 VA Frequency rating 50/60 Hz Rating marks UL, CSA Built-in fuse clips Secondary side Thermal class 105 degrees C (221 degrees F) Power transformers change voltage from a supplied voltage to a required voltage. They also isolate control circuits from power and lighting circuits, which reduces electronic interference. Transformers accommodate specific primary voltages and currents, and supply specific secondary voltages and currents. Power transformers are used in a wide range of applications, such as home electronics power supplies, machine tools, and the distribution of electricity.

Siemens manufactures electronic products for building automation, industrial drives, lighting, energy generation, medical equipment, and rail transportation. The company, founded in 1847 and headquartered in Munich, Germany, meets International Standards Organization (ISO) standards 14001, 9001 and TS 16949.

Features

  • Reduces 240 x 480, 230 x 460, or 220 x 440 V (primary voltage) to 120/115/110 V (secondary voltage)
  • Rated up to 75 VA
  • Silicon steel-laminated core and copper magnet wire for increased transformer efficiency
  • Epoxy-encapsulated to resist moisture, dust, and industrial contaminants
  • Built-in fuse clips on secondary side save panel space and wiring time because they do not have to be manually installed in the field
