BUZZ BOX, BLASTING MACHINE/TESTER BB-75

The BB-75 is an advanced, compact high-energy capacitive discharge blasting machine capable of initiating a minimum of 75 EBCs (tested through 340 ohms). Bridgewire and firing line continuity is testable through the integrated haptic (tactile feedback) circuit tester with redundant LED indication. Intrinsic safeties include automatic abort, internal shunt, boot-protected switches, touch-proof output terminals with downward facing inputs, and fuse protected testing circuit.

Detalles Adicionales

320 VDC @ 10 Joules (min) firing energy (max output 340 VDC @13 Joules)

Capable of firing a minimum of 75 EBCs connected via 3000 of two-conductor 18 ga. copper firing line (tested through 340 ohms)

Uses standard 9-Volt battery (included)

Built-in bridgewire testing circuit

Less than 800 µA (micro amps) maximum current draw, barely 1/60th the maximum allowable safe testing current of 50 mA, as established by MSHA.

Testing circuit protected by 50mA fuse

The ONLY blasting box featuring a built-in haptic (tactile feedback) bridgewire continuity tester

Strong vibrating response provides positive indication, even in direct sunlight and noisy environments

LED visually confirms continuity and indicates a low-battery

Small and lightweight

3.5 wide x 6.5 long x 1.2 thick; 11.5 ounces (with battery) (8.9 cm x 16.5 cm x 3 cm; 326 g)

Easy to use

Connect firing line to high-voltage binding posts

Hold down ARM switch to charge blasting circuit

Once the Super-Bright Ready LED lights solid (flashes during charge), press FIRE button to send high-energy pulse down firing line

Intrinsically safe design

Internally shunted output terminals help protect EBCs from stray EMI remain shunted until instant of firing

Auto abort discharges the capacitor upon release of ARM button (prior to firing)

Bridgewire testing circuit current is less than 1 mA (795 microamps average)

Fuse protected testing circuit cannot provide more than 50 mA (serial numbers 100+)

Touch-proof output terminals with downward facing inputs reduce risk of shock

Rugged enclosure

Black ABS case with bright-red/orange rubber boot, and sealed switches

Shock and weather resistant (not designed for wet use due to high-voltage output)
