The 257xR ballast analyzers have been adopted by ballast/lighting manufacturers worldwide because of their greatly enhanced technological capabilities, greatly reduced setup and maintenance requirements and low cost of ownership.

With the 257xR, up to four tubes and four ballasts can be tested in a fraction of a second for every key parameter, including peak inrush, striking and light efficiency (when used with a light monitor.) With a capacity of 2,000 measurements per second on each of up to 30 signals, the only limitation to testing throughput is the speed of your production line.

The 257xR can be used in stand alone or computer controlled environments. It allows the user to simultaneously measure all pins on all tubes, independent output measurements, 12 voltages and 12 currents, (i.e. independent tube V and I measurement, independent filament V and I, for each tube that is configured). Continuous sampling at up to 2 Msps ensures that even the shortest transient events are measured.

The 1500 Line/Load Chassis features 12 slots per chassis for most combinations of the following:

• Line switches, programmable from 0-360° turn on.
• Fixed Resistance Tube Load Cards, 100W, 200W, 300W.
• Variable Resistance Load Cards, 60W.
• Fixed Triple Resistance Load Cards, 60W.
• Conduction Angle Controller, programmable from 0-360° conduction.
• Tube Load Card allows user to connect actual tubes or custom loads.
