Technical Specifications

 TYPE Circuit-breaker analyzer
 PHYSICAL SPECIFICATIONS 18”W x 7”H x 15”D (45.7 cm x 17.8 cm x 38.1 cm); Weight: less than 19 lbs (8.6 kg)
 INPUT POWER 3 Amps, 100 – 120 Vac or 200 – 240 Vac (factory pre-set), 50/60 Hz
 DRY-CONTACT INPUTS 3 dry-input channels; each channel detects main and insertion-resistor contacts
 TIMING WINDOWS 1-second, 10-seconds, or 20-seconds
 TIMING RESOLUTIONS ±100 micro-seconds @ 1-second duration, ±1.00 milli-seconds @ 10-second duration, ±2.00 milli-seconds @ 20-second duration
 TIMING ACCURACY 0.05% of reading ±0.1 ms @ 1-second duration
 DRY-CONTACT CHANNEL PROTECTION Fuses protect all isolated power supplies; all contact inputs are grounded until test; input channels are protected against static discharge
 CONTACT DETECTION RANGE Closed: less than 20 ohms; Open: greater than 5,000 ohms
 TRIGGER INPUT VOLTAGE Open/Close: 30 – 300V, DC or peak AC
 VOLTAGE SENSING INPUT RANGE V1: analog input; 0 – 255V, DC or peak AC; Sensitivity: ±1V
V2: voltage presence/absence detector input; 30 – 300V, DC or peak AC
 BREAKER OPERATIONS Initiate Open, Close, Open – Close, Close – Open, Open – Close – Open
 INITIATE CURRENT READING RANGE One, non-contact, Hall-effect sensor, 0 – 20 amp range, dc to 5Khz
 TRAVEL TRANSDUCER INPUT 1 digital travel transducer channel; Linear range: 0.0 – 60.0 in (±0.005 in.); Rotary range: 0 – 360 degrees (±0.006 degrees)
 CONTACT TRAVEL POINT DIFFERENCE Measures “slow-close” contact-point distances; results can be printed
 DISPLAY Back-lit LCD Screen (20 characters by 4 lines); viewable in bright sunlight and low-light levels
PRINTER Built-in 4.5-inch wide thermal printer can print both graphic contact travel waveforms and tabulated test results
INTERNAL TEST RECORD STORAGE Stores up to 100 test records and 99 breaker test plans
 COMPUTER INTERFACE RS-232C port (19,200 baud)
 PC SOFTWARE Windows® XP/Vista-based Breaker-Analysis software is included with purchase price
