Page 8: Important Guidelines
Important Guidelines Introduction The important guidelines for operating the ENDURO 250 Volt Power Supply are provided in this section. We recommend that you carefully review these guidelines before operating the instrument. Important For best results, do NOT use the ENDURO 250 Volt Power Supply at its maximum electrical load limits. -
Page 9: Operation
Operational Modes Introduction The ENDURO 250 Volt Power Supply is designed to operate under different modes, Constant mode or Programming Mode, depending upon your electrophoresis needs. Use the Constant Voltage, Constant Power or Constant Current Operation for applications that require only one specific voltage limit, current limit, and power limit continuously during the entire duration of electrophoresis. - Page 10 7. Press START/PAUSE key to start electrophoresis. 8. Press the START/PAUSE key again to temporarily interrupt power to ongoing electrophoresis without terminating the operation along with LED flashing. 9. Press the STOP key to stop electrophoresis. 10. If the parameters need to be changed during the run you must stop electrophoresis by pressing the Mode key.

Power Limiting Watts is a function of voltage and current W=IV. If voltage is increased watts will also be increased depending on the gel system, R should be a constant. Watts will be reflected by the heat generated during a gel run. The power limiting function may be used when running sequencing gels to remove the APS from the wells and to heat the gel to an optimal temperature for DNA separations. - Page 13 Display shows Turn the Power switch off and on again; “OVER VOLTAGE” restart application. If you cannot restart the instrument, turn off the power, disconnect the power cord from the outlet, and contact Technical Service. Operation stops Ground leak detected 1.

Page 14: Operational Electrical Parameters
Operational Electrical Parameters Power Considerations Electrophoresis is the migration of a charged particle under the influence of an electrical field. The power supply output parameters voltage, current, and power are related by the following two equations: Voltage (V) = Current (I) x Resistance (R); (V=IR) Power (W) = Current (I) x Voltage (V);... -
