SIMCHECK II Power Supplies
- Q. If necessary, can I replace the RAMCHECK
or SIMCHECK II power supply with one that we have in house, or with one
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.
- 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
- 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.
