Description

DRC-180 is a 180W AC/DC DIN rail type security power supply series. In addition to the primary output, there is a charger output with a smaller rated current, enabling the backup power supply application the security access systems require. DRC-180 accepts the universal input between 90VAC and 264VAC, and supplies 13.8VDC and 27.6VDC at output, respectively. With the efficiency up to 90%, it can operate with air convection cooling under -20°C through 70°C. In addition to the key protection features such as overload protection, over voltage protection, battery low cut off, and battery reverse polarity protection (by fuse), the alarm signal for AC OK and battery low signaling is provided, via relay contact output, to facilitate the system design.

NOTE	1. All parameters NOT special y mentioned are measured at 230VAC input, rated load and 25 C of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1 p F & 47 p F parallel capacitor. 3. Tolerance : includes set up tolerate, line regulation and load regulation. 4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time. 5. Please refer to suggested Application 2(2) – (3) in page 4. 6. The ambient temperature derating of 3.5t/1000m with fanless models and of 5t/1000m with fan models for cperating altitude higher than 2000m(6500ft). 7. The power supply is considered a component which wiH be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies?’ (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf ) Product Liability Disclaimer : For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx

Suggested Application

1. Backup connection for AC interruption
   (1) Please refer to the Fig1.1 for suggested connection.
   The power supply charges the battery and provides energy to the load at the same time when the AC main is OK.
   The battery starts to supply power to the load when the AC mains fails.

Fig 1.1 Suggested system connection

2. Alarm signal for AC OK and Battery Low

1. Alarm signal is sent out through ” AC OK ” & ” Battery Low ” pins.(relay contact type)
2. An external voltage source is required for this function. The maximum applied voltage is 30V and the maximum sink current is 1A.
3. Table2.1 explains the alarm function built in the power supply

Function	Description	Output of Alarm
AC OK	when the power supply turns ON	Closed
	when the power supply turns OFF	Open
Battery Low	when the voltage of battery is under A:11V, B:22V	Closed
	when the voltage of battery is above A:11V, B:22V	Open
