SIMCHECK II Power Supplies

1. Q. If necessary, can I replace the RAMCHECK or SIMCHECK II power supply with one that we have in house, or with one acquired locally?
   A. We strongly recommend that replacement power supplies be acquired from us, as we do fine tuning of lower voltage to reduce the heat that is dissipated inside the memory tester. However, if you have technical knowledge of power supplies, you may replace it with a new one, only if it is polarized in the same manner as the original Power Supply (center positive) AND it meets the output rating for CURRENT and VOLTAGE. For RAMCHECK the power supply's voltage must NOT exceed 6.75-6.90V at actual current of 4Amp. We use a 7.25V/4.4A power supply which is carefully adjusted for 6.85V at 4Amp. For SIMCHECK II, the voltage must not exceed 7.5V at 3Amp.
   
2. Q. Can the old SIMCHECK power supply be used with SIMCHECK II?
   A. NO. The polarity of the SIMCHECK II power source is reversed compared to the SIMCHECK PLUS, therefore only use the power supply that your SIMCHECK II is packaged with. A special diode protects SIMCHECK II if a wrong power supply is used.
   
3. Q. Can the RAMCHECK power supply be used with SIMCHECK II and vice versa?
   A. NO. RAMCHECK requires slightly lower voltage, as detailed above, in order to reduce the heat inside the unit. During factory upgrade from SIMCHECK II to RAMCHECK, our technicians carefully adjust the original power supply for RAMCHECK levels, or completely replace it.
