BLASI – NUM 320
The BLASI NUM 320 is a precision power regulation module for automatic revolving door control systems, providing stable voltage output to sensitive electronics including TA-4 logic boards and peripheral controllers. This compact DC-DC converter maintains consistent 24VDC supply across wide input voltage fluctuations while protecting against surges, brownouts, and electrical noise common in commercial power systems. Featuring short-circuit protection, thermal shutdown, and diagnostic indicators, it ensures uninterrupted operation of safety circuits and control functions essential for certified 24/7 revolving door performance in high-traffic environments.
Product Details
The BLASI NUM 320 power regulation module delivers clean, isolated 24VDC power to critical control electronics within TA-4 revolving door systems, employing switch-mode conversion technology to maintain precise output voltage despite ±20% input variations typical of commercial electrical service. High-efficiency design minimizes heat generation while comprehensive protection circuits guard against overvoltage, undervoltage, and transient spikes prevalent in Dubai’s grid conditions.
Switching pre-regulator feeds linear post-regulators dedicated to analog and digital circuits, eliminating cross-talk and ensuring noise-free operation of safety monitoring and position encoder systems. Integrated EMI filtering prevents interference with proximity sensors and radio controls while diagnostic LEDs provide immediate power status verification during Service-IBS troubleshooting sessions.
Field-replaceable design with quick-disconnect terminals enables rapid restoration of power distribution without system downtime. Essential for maintaining uninterrupted safety functionality and control precision required for regulatory compliance in hotels, office buildings, hospitals, and retail facilities where power quality directly impacts passenger safety and operational reliability.
