Atte buffer switch-mode power supply AUPS-70-120-OF — model 19213

The Atte buffer switch-mode power supply AUPS-70-120-OF provides a regulated DC output and buffering for connected low-voltage equipment. Designed as an impulse (switch-mode) converter with integrated buffering, this unit delivers stable power to devices that require smoothing of supply disturbances and temporary hold-up during brief mains interruptions. The product is intended for installations where continuous, regulated DC supply is important for proper operation of electronics.

Advantages

The Atte AUPS-70-120-OF integrates switch-mode conversion with buffered output to reduce voltage fluctuations and provide cleaner DC power compared with direct mains-fed supplies. Its compact design allows mounting within control cabinets and equipment enclosures, while efficient conversion reduces heat generation and standby energy consumption. The buffered output improves reliability of connected systems by maintaining supply during short interruptions and by limiting inrush and transient effects.

Suitable for

• Security systems: cameras, alarm control panels and sensors
• Access control equipment: electric locks, readers and controllers
• Low-voltage electronic modules requiring regulated DC supply
• Industrial control circuits and instrumentation with brief hold-up needs

Key specifications

• Type: buffer switch-mode (impulse) power supply providing buffered DC output
• Output characteristics: regulated DC suitable for powering low-voltage electronic devices
• Buffering function: holds output during short mains disturbances to prevent device resets
• Mounting: suitable for installation inside control cabinets and enclosures
• Thermal behavior: efficient conversion to minimize heat generation under nominal load

How to use

Install the unit following applicable electrical safety standards and local codes. Mount the supply in a ventilated area inside the equipment cabinet, secure it mechanically, and make electrical connections using appropriately rated conductors. Connect the AC input to the building supply and connect the DC output to the protected devices, observing correct polarity. If external batteries or additional buffering are used, follow battery manufacturer and system integration instructions. After wiring, verify output voltage and correct operation of connected loads before leaving the installation unattended.

Usage recommendations

For reliable operation, keep the unit free from dust and ensure adequate ventilation. Use the buffer supply within its specified load range, and avoid prolonged operation beyond rated capacity. Periodically inspect connections for corrosion or loosening and verify output voltage stability as part of routine maintenance.
