Safety Considerations Read and understand this manual completely before attempting to set up or use this instrument. This equipment has been designed and tested to conform to CSA1010 safety standards, as applicable to laboratory instrumentation. This applies only to the EPS-3000P-II(V) when used as specified in the documentation, in its intended applications, with CBS Scientific approved electrophoresis apparatus only. Usage in any other manner may not provide similar performance or safety protection.
Introduction Thank you for selecting a CBS Scientific EPS-3000P-II(V) Electrophoresis power supply. This manual describes the operation of the EPS-3000P-II(V). The power supply that you have purchased is the most productive and easy-to-use unit available anywhere. This manual should answer any questions that might arise in operating your power supply; however, don’t hesitate to call our CBS Scientific Technical Support at 1-800-756-5737 or email us at TechnicalService@cbssci.com if you need any assistance.
Specifications AC input Power 100-240 VAC, 50-60Hz, 500VA Max Environmental Operating temperature: 0-40°C, 0-95% R.H. non-condensing Altitude: 2000m Overvoltage category II, IEC664 Pollution degree 2, IEC664 DC output Power 20-3000VDC, 400W Max 1-400mA, 400W Max Ripple: ± 1% Drift: ± 1%, after 30-minute warmup Power Cord Specifications Power Supply cat.
Getting Started Select a location that allows for 3” clearance behind the power supply, and comfortable reach of the front panel controls and cell connections. Do not block the vented area of the case - on the front bottom of the unit, or the fan area at the rear. Connect the power supply using a cord appropriate for the mains supply.
temperature as an upper limit is when the unit is in the Constant Temperature mode (See Constant Temperature Operations section for details). To change the control mode, press the Exit key. From the resulting screen, select the new constant parameter using the function keys to the right of the display. After selecting a control mode and setting the limit and timed run parameters if desired, press the Run key to energize the power supply output.
Constant Power Operations From the mode selection screen, select constant power operation by pressing the appropriate function key located to the right of the display. To get to the selection screen from an operating screen, press Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key and selecting MANUAL. The EPS-3000P-II(V) will display the last saved setpoint for constant power mode.
Volt-Hour Operations It is possible to enter an amount of volt-hours for the power supply to provide power, after which it will automatically shut off. Volt-hours is the integration of voltage over time. Use volt-hour control to provide consistency between runs. Set up a constant mode setpoint and limits as described above. Enter a volt-hour duration of 09999 volt-hours. A volt-hour duration of zero effectively disables volt-hour run mode.
entering a new value. The EPS-3000P-II(V) will not accept any parameter outside of the allowed range. Press Clear to re-enter an appropriate value. When all the parameters of the step are as desired, press Exit to return to the step screen. The newly entered parameters will be displayed in the selected step. To add a step after the selected step press the function key labeled ADD. Enter parameters for the step as for EDIT, pressing Exit when complete.
Troubleshooting and Error Indications The EPS-3000P detects and reports several events and conditions that are considered errors. The EPS-3000P will stop any run in process and display “ERROR XX” where XX is one of the below listed errors. When the EPS3000P is displaying an error indication, press the gray ON/OFF key to clear the error and return to setup mode, or press the Run key to resume the run (after correcting the cause of the error).
EPS-3000P Warranty Statement The CBS Scientific Company warrants to the direct purchaser that the EPS-3000P will be free from defects in material or workmanship for a specified warranty period. During that period, CBS Scientific will repair or replace the product or provide credit, at its sole option, upon prompt notification and compliance with its instructions. For EPS-3000P-II(V) power supplies that specified period is 48 months from manufacturing date.
