Key Features & Benefits

• Avtron Helidyne™, helically wound, corrosion resistant, chromium alloy are carefully selected to operate at conservative temperatures, typically ½ of maximum continuous rating of wire, to provide extended, reliable performance, eliminating the need for a "cool down" period. 
• Variation in resistance due to temperature is minimized by maintaining conservative watt densities providing higher accuracy.
• Avtron inductive reactors are designed and built with an iron core and air gap combination that limit magnetic flux levels to assure a power factor of less than 0.05 at rated voltage and frequency. Single and 3-phase Iron core reactors are designed for a 130°C rise in a 50°C environment with a maximum of 5% waveform distortion and 0.05 power factor.
• Avtron Load Banks are built to last with heavy gauge aluminized steel construction with powder-coat paint, and heavy-duty industrial blowers. Portable load banks are built to resist vibration encountered during transportation.

K595

The K595 is a three-phase, 120/208 VAC load bank, rated at 41 KW maximum load. The K595 is designed for indoor use and is Wye connected which allows for single phase testing as well. The K595 is a versatile load bank designed for testing of larger 400 Hz AC power supplies..

K696

The K696 is designed for three-phase loads up to 187 KW. The K696 is suitable for testing 120/208 VAC, 400 Hz power supplies and ground power units (GPUs).

Permanent Load Banks

For demanding applications requiring high capacity load testing in outdoor installations, these Load Bank models provide the best accuracy, versatility, and reliability.

T103

The T103 is a three-phase, Wye configured resistive/reactive load bank designed for outdoor installation. The T103 has a capacity of 123 KW resistive (41 KW / ph) and 93 KVAR reactive (31 KVAR / ph, lagging PF) with infinite resolution. It is designed for 120/208 VAC, 400 Hz applications. The T103 is the perfect load bank for testing 400 Hz alternators up to 150 KVA.

K675A

Avtron’s K675A is a three-phase resistive load bank designed for outdoor installation. The unit features automatic control (via PLC) and is Wye connected. The K675A has a capacity of 213 KW resistive (71 KW / ph) with 7.2 watts/ph resolution. It is designed for 120/208 VAC, 400 Hz applications. In combination with the K843 reactive load bank(described below), the K675A is the perfect load bank for testing 400 Hz alternators up to 250 KVA.

K843

The K843 is a three-phase reactive (inductive) load bank designed for indoor installation. It is designed for automatic control via PLC communication with a Wye load configuration. The K843 has a capacity of 213 KVAR reactive (71 KVAR / ph, lagging PF) with 33 watts/ph resolution. It is designed for 120/208 VAC, 400 Hz applications. When combined with the K675A resistive load bank (described above), the user can test 400 Hz power sources up to 250 KVA at a 0.8 PF.
