TRANZISTOR BLASTING MACHINE VTR-1
	dimensions 145 x 70 x 50 mm weight 310 g capacitor capacity 100 µF capacitor voltage 400 V capacitor energy min. 6 J protection IP 40 power source: accumulator 6 V RV at „S“ / n1 155 Ohm RV at „Sicca“ / n1 65 Ohm + accumulator charger

Description:

• Intended to ignite electrical bridge detonators of type SO and Sicca in serial and serial/parallel connection.
• Built into a case of thermoplastic material.
• Powered by rechargeable alacline accumulator with voltage 6 V.
• Controls are placed on front panel - two buttons, two indicators and working mode switch.
• Main switch is located on left side of the device.
• Green indicator will light up after switching on the main switch, which indicates suitable accumulator status.
• Device is activated by switching the switch to left position (or by switching the key on the right side on second version of the device) and by pushing the "Charge" button.
• When the capacitor is charged to working voltage 400 V, it's indicated by blinking red indicator on the control panel.
• To reach full capacitor voltage it's required to hold the "Charge" button for about 5 seconds since start of indicator blinking.
• Device is protected against overcharging of the capacitor to higher voltage than nominal by circuit, which holds set voltage even if further charging is active (voltage stabilizer).
• When switch is switched to right position (or key on the right side on second verion of device), shorting the clamps is unblocked and blasting machine is ready to fire.
• By pushing the "Fire" button the capacitor is discharged through leads connected to output clamps and connected detonator is ignited.
• Whole circuit board is sealed in special material to enhance water and vibrations resistance.
• Product number and load characteristics for "S" and "Sicca" detonators are on back side.
• Blasting machine is shipped with leather protective jacket with strap and line adapter for accumulator charging.
