Farnell stabilised switch-mode power supply F2615
FARNELL STABILISED SWITCH-MODE POWER SUPPLY
Nominal Output Voltage: 6V d.c.
Voltage Adjustable Range: 4 - 6V d.c.
Approximate SIZE: 15 x 8.5 x 3 cm : Apr WEIGHT: 0.8kg
FOUND ON THE WEB WHAT APPEARS TO BE A SPECIFICATION SHEET FOR THIS POWER SUPPLY I HAVE INCLUDED A COPY AT THE END OF THIS DESCRIPTION, IT MAY PROVE USEFUL
I HAVE A NUMBER OF THESE POWER SUPPLIES,SO YOU MAY NOT GET THE ACTUAL ONE PICTURED
TESTED WORKING BEFORE DISPATCH
HOWEVER DUE TO THE POWER SUPPLY BEING IN LONG TERM STORAGE I AM SELLING FOR SPARES OR REPAIR
I thought I might take the opportunity to give a little information on the power supply.
There is a .1 ufd capacitor C101 next to the fuse holder which sometimes gives trouble (and causes the fuse to blow) if the power supplies have been in storage for sometime which this as been. Although the power supply was tested before dispatch I would advise that you replace this components in the interest of reliability.
THE POWER SUPPLY HAS BEEN VERY WELL MADE BY FARNELL INSTRUMENTS
GRAB YOURSELF A GREAT BARGAIN!!!
Farnell, G6-5M, 4 - 6 V d.c., 30W adjustable switch mode power supply. Specification:
- Mains Input: 220 - 240V or 115 - 120V (selector switch 45 - 440Hz)
- Nominal Output Voltage: 6V d.c.
- Voltage Adjustable Range: 4 - 6V d.c.
- Output Voltage Regulation: 0.1% max. Variation for worst-case combination of 0 to 100% load change and 220V - 10% to 240V +10% or 115V -10% to 120V +10% line Change.
- Ripple and Noise at full load (30MHz bandwidth): Less Than 10mV r.m.s.; 50mV pk to pk.
- Temperature Coefficient: + 0.01% per C typical.
- Transient Recovery Time: Typically 1mS for output to recover within 50mV following a 10% to 100% or 100% to 10% load change of 5uS risetime. Typical instantaneous output deviation 400mV.
- Operating Ambient Temperature Range: -10 C to +55 C for full load output current. (Convection cooled free air rating.)
- Max. Operating Ambient Temperature: 70 C max. Output current should be derated linearly from full load at 55 C to half load at 70 C.
- Storage Temperature Range: - 40 C to + 85 C
- Hold-up Time: Output will be maintained for the duration of a missing mains cycle (28mS) at maximum output current and 220V -10% or 115V -10% mains input, when the output is at 6V for 6V nominal units or nominal +5% for other units. Graphs are supplied in booklet.
- Switch on Surge: Less than 80A
- Switch on Time: Output established within 30mS
- Insulation: Tested at 2.1kV peak for 1 minute between a.c. input and d.c. output, with output terminals and earth connected together. + 250V d.c. continuous rating between output and earth. Tested to 500V d.c. for 1 minute.
- Remote Sensing: Up to 5V max. drop in each output lead permitted. However unit output terminal voltage must not exceed 6V for nominal 6V units, or nominal +5% for other units.
- Efficiency: Better than 70% at full load.
- Overload Protection: Current limiting set at 110% + 5% of full load current with the short circuit current 100% - 130% of full load current.
- Overvoltage Protection: Set at nominal output voltage + 20%. Disables control circuit and output falls to zero. Reset by interrupting the mains input supply.
- Fuse: The a.c. input is fused (fuse type 1A. T.)
- Series and Parallel Operation: Any number of units with the same output voltage may be connected in parallel. Outputs of similar current rating may be connected in series up to a maximum total output voltage of 250V.
- Dimensions (including terminals): 145 x 88 x 33mm- Weight: 750g
