Available with IEC/ISO 17025 Certificate of Calibration
HIT 1.2-K-UC Isolation Transformer
above: Dual voltage isolation transformer
Product Details

As a general purpose dual-voltage isolation transformer for step-up (120 to 240 VAC), step-down (240 to 120 VAC), or straight 1:1 isolation (120 to 120 VAC or 240 to 240 VAC). Models with a suffix “UC” are provided with a safety jack for access to the transformer secondary center tap (connected to the transformer center tap only in the 240 VAC output setting). This connection may be used in conjunction with a Dielectric Voltage Withstand test.
HIT-5.0K-U Isolation Transformer
above: Dielectric Voltage Withstand
Product Details

As a general purpose dual-voltage isolation transformer for step-up (120 to 240 VAC), step-down (240 to 120 VAC), or straight 1:1 isolation (120 to 120 VAC or 240 to 240 VAC). Models with a suffix “UC” are provided with a safety jack for access to the transformer secondary center tap (connected to the transformer center tap only in the 240 VAC output setting). This connection may be used in conjunction with a Dielectric Voltage Withstand test.
Input/Output Connections Detachable power supply cords, with bare leads for panel connection Overall Dimensions 28 in. D x 21 in. W x 15 in. H (71 x 54 x 38 cm)
Environmental Ratings 10-30 °C, indoor use only Pollution Category II
Overall Weight(without cords) 185 lbs. (84 Kg)
HIT-7.5K-U Isolation Transformer
above: Dual voltage "international" isolation transformer
Product Details

This transformer is a general purpose dual-voltage "international" isolation transformer = for step-up (120 to 240 VAC), step-down (240 to 120 VAC), or straight 1:1 isolation (120 to 120 VAC or 240 to 240 VAC).

This isolation transformer is constructed with double insulation which includes an insulated ground shield between the primary and secondary windings. The secondary winding is not grounded (no neutral).

NOTE: In many countries "ground" is referred to as "earth." You may interchange the word "earth" with "ground."

NOTE: The input voltage rating has a ± 10% Tolerance = it may be used for 110/220 VAC, 115/230 VAC, or 120/240 VAC application.
Input/Output Connections Detachable power supply cords, with bare leads for panel connection Overall Dimensions 28 in. D x 21 in. W x 15 in. H (71 x 54 x 38 cm)
Environmental Ratings 10-30 °C, indoor use only Pollution Category II
Overall Weight(without cords) 185 lbs. (84 Kg)

Variac Variable Transformers
above: Variac Transformers
Product Details

Also known as a varlac, this device allows you to adjust the input voltage to the product you are testing. If you don't need frequency adjustment, this is a much lower cost alternative to a power source. Output is fused. Single phase units noted below, 3 phase units available. Standard models include input voltages from 120VAC to 480VAC. Frequencies to 2000 Hz can be accommodated. Special units for voltages to 1000 VAC are available.
Model Input VAC Output VAC Amps Hertz
3PN501 120V 0-140V 5A 50/60 Hz
3PN1010 120V 0-140V 10A 50/60 Hz
3PN2210 120V 0-140V 22A 50/60 Hz
3PN1220 240V 0-280V 5A 50/60 Hz
3PN1520 240V 0-280V 9.5A 50/60 Hz
