CURRENT SINK CAPABILITY
BHK-MG 40W Series power supplies are able to sink up to 5% of the nominal current when in
voltage mode and greater than 75% of the unit's maximum rated current when in current mode.
The fixed current mode sink value is model dependent and has a tolerance of 10%. When the
BHK-MG 40W is in sink mode, the unit displays the word “Sink” and the sink current value (neg-
ative) on the front panel display. This capability is useful in applications such as capacitor test-
ing, where the sink capability allows the rapid discharge of the device under test, permitting
subsequent tests to be started earlier, thus increasing the throughput of the testing process.
The sink current in current mode is quite stable, allowing this feature to be used with the dis-
charging process to determine the value of a capacitor under test by measuring the discharge
time, using the formula C = T x I / V (the charge time, which is more accurate, can also be used
in the formula), where
T = discharge or charge time
V = change in voltage from fully charged to fully discharged, or vice versa.
I = discharging or charging current (BHK-MG charging current has a tolerance of
0.05% of nominal value, discharge current has a tolerance of 10% of nominal value)
The value of the capacitor under test can be calculated directly by measuring T and either using
the above formula and the appropriate tolerance for I, or by comparing T to that of a known
capacitor value.
