4. Features
•
fast heat up thanks to high frequency heater technology
•
electronic temperature control
•
password lock
•
auto-sleep function to save power and extend bit life
•
sensor and heater fail notification
•
LCD display with digital temperature scale (°C or °F)

•
ceramic heating element with temperature sensor
•
HEATER/SENSOR FAILED DETECTION: if the sensor circuit fails, the display reads "S--E" and heater
power is cut. If heater circuit fails the display will read "H--E" and heater power is cut.
•
TEMPERATUE "LOCK-OUT" FEATURE: the temperature can be locked with a password which might be
useful in a production line.
•
ESD SAFE AND SPIKE FREE CIRCUITRY: the "Zero Voltage" electronic switching design also protects
voltage and current sensitive components (CMOS devices, etc.) against overcurrent and transient
voltage spikes.
•
LIGHTWEIGHT SOLDERING IRON: ergonomic mini handle that stays cool and prevents operator
fatigue.
•
isolated power supply: high-quality 230Vac transformer designed for lead-free soldering

6. Description
•
This soldering station is designed to meet the present and future needs of the electronic production
industry. The VTSSC74 is engineered to meet the stringent demands of hobbyists, maintenance
personnel and production people alike.
•
A high-quality sensor and heat transfer technology ensure precise temperature regulation which is
essential for making consistent, reliable soldered connections.
•
The aluminium alloy housing has several advantages: strong, good heat sink and very resistant to
electro-magnetic interference.
•
The VTSSC74s' electronic circuitry enables the user to set soldering temperatures between 100 and
520°C (212 to 968°F) without having to replace the tip or the heating element. The temperature is
maintained to within ± 3°C (± 5.4°F) of the normal operating temperature by a thermocouple sensor
placed in the head of the heating element. The 90W power results in a rapid heat-up and fast
recovery.
•
The revolutionary "zero voltage" switching design also protects voltage- and current-sensitive
components (CMOS devices, etc.) against the damaging current and transient voltage spikes
commonly produced by less efficient, mechanically switched stations. The heating elements are
galvanically isolated from the electrical supply by an isolating transformer that prevents the system
from using a max. tension higher than a (safe) 32Vac.
