Acopian 48V redundant linear regulated power supply
Acopian 48V Redundant Linear Regulated Power Supply
Acopian 48 Volt Redundant Power Supply Model R48H16AHKS
The unit has been tested and guaranteed to be fully operational. This particular unit comes with several options:
* 2 Amp meters + 2 Volt meters
* Chassis slides for rack mount
The current list price for this Power Supply sold at Acopian with the listed options is over $2100.00, so this is a great opportunity for you to pick up an excellent quality power supply at a much lower price.
Output Redundancy: Each Redundant Power Package contains two identical power supplies with their outputs interconnected through a diode switching arrangement that will detect any fault condition, isolate it from the system output, and pass only the output of the other supply with no interruption of output power during the transition.
Applications: Redundant Power Packages should be considered for any equipment where the highest attainable reliability is essential, and an unexpected loss of power would be disastrous. Such applications include communications systems (both voice and data types), computer systems (volatile memory systems in particular), process controls, utility and municipal systems, and security/safety alarm systems.
Serviceability: A defective power supply can be rapidly and safely changed while the Redundant Power Package continues to furnish uninterrupted power to the load. All input, output and alarm-contact connections are at the rear of the assembly for Rack Mounting models or on the front for Wall Mounting models.
Monitoring Circuitry: The Redundant Power Package contains two voltage monitoring circuits with relays, contacts of which are available to control external failure alarms or other circuitry. The contact wiring of the two relays is connected in cascade, to simulate a single set of Form C contacts which switches if the output voltage of either power supply decreases by more than 2.0 volts (3.0 volts for outputs over 48 volts) from the nominal rating.
Over voltage Protection: Automatic recovery. Each power supply contains an over voltage protection circuit, to assure that neither power supply output will significantly exceed the nominal output voltage rating under any condition, including incorrect application and misadjustment.
Specifications: Input Voltage: 105-125 VAC, 50-400 Hz, single phase.
A separate set of AC input terminals is provided for each power supply, so that if two sources of AC input power are available, one may be used for each supply and so reduce the possibility of output dropout due to loss of input power. Load Regulation: 0.05% (Dynamic regulation - does not include 0.2 volt shift which occurs during switching to lower-set backup supply.)
Line Regulation: 0.05% Ripple: 1 mV rms. Remote Voltage Sensing: Provision for sensing the output voltage across the load, so that drops in the load line are compensated, is a standard feature. Load Protection: Overvoltage protection. Overload/Short Circuit Protection: Foldback current limiting with automatic recovery. Polarity: Output is floating; either positive or negative output terminal may be grounded or floated up to 300 volts above ground. Voltage Monitor Circuits: One for each power supply. Relay contacts switch when output voltage decreases approximately 2 volts from the nominal rating (approximately 3 volts for outputs over 48 volts), and may be used to control an external failure alarm. Alarm Relay Contact Ratings: 120 VAC, 8A / 60 Vdc, 1A. (To comply with SELV requirements, limit switched voltage to 60 Vdc / 42 VAC.) Output Metering: A separate voltmeter for each output (standard). Ammeters available; see Options.
