Power supply converts the AC mains into DC
Power source for internal units. Channel 1/2/3
control and produce the actual DC output. Displa
shows output and OVP level, receiving feedback
from each channel. Internal components are placed
on four printed circuit boards, A ~ D.
Detailed description of each module starts on the
next page.

EMI Filter
Other than deleting conduction EMI (electromagnetic interference), the EMI unit contains
protective circuits such as Inrush current limit
resistor and Surge absorber. Internal units are
protected under power-up sequence, normal
Rectifier / Doubler
operation, and AC mains fluctuation.
The Rectifier unit converts AC mains into DC
Power source. For 115V±15% AC, double-wave
rectification is used; for 230V±15% AC, full-wave
rectification. An internal selector automatically
switches the rectification circuit accordingly. The
final DC Voltage reaches 240V ~ 370V.
CH1/2 Power
Stage
The Power stage for Channel1 and 2 produce the
outputs using the combination of Half-bridge
converter and Linear regulator. The Half-bridge
converter adopts PWM (pulse-width modulation)
with high frequency switching. The Linear
regulator adjusts the output Voltage down to 0V.
CH1/2 AUX Power
The AUX Power for Channel 1 and 2 produces the
power source for auxiliary devices, such as
analog/digital controller, relay, LED display, and
cooling fan. Altogether four pairs of power source
are generated for different purpose: ±12V, +5V,
and +12V.
CH3 Power Stage
The Power stage for Channel 3 produces both the
channel output and the power source for auxiliary
devices. It uses the combination of Flyback
converter and Linear regulator, carrying lower
efficiency compared to Channel 1 and 2. The
flyback converter also produces ±12V for ICs and
4~8V settable Voltage.

The Controller for Channel 1, 2, and 3 takes care of
the interface between SPD-3606 and users. Several
sub-units comprise the Controller, including:
• Feedback control unit
• OVP setting unit
• Fan control unit
Detailed description of each unit follows.
The Feedback control unit receives the control
signal for Voltage/Current output level and the
level feedback signal from the actual output. The
difference between the two signals are amplified
and used as the control signal for the Power stage
to achieve stable output level.
The SVR (small variable resistor) sets the
protection point so that the OVP setting unit shuts
down the output when the output Voltage level
exceeds the configured level.
Using NTC (negative temperature coefficient)
resistor, the Fan control unit changes the control
Voltage for the cooling fan according to the
temperature change, achieving low-noise and
linear speed control.
The Tracking controller controls Channel 2 output
level when in tracking series or parallel mode. In
tracking series mode, Channel2 output Voltage is
controlled by Channel1 output Voltage level. In
tracking parallel mode, Channel2 output Current
is controlled by Channel1 output Current level.
The LED display shows the Channel 1/2/3 output
Voltage/Current level. The A/D converter
changes the analog signal coming from each
channel into digital format to be displayed.

CV/CC Crossover Characteristics
Background
SPD-3606 automatically switches
voltage mode (CV) and constant current mode
(CC), according to load condition.
When the current level is smaller than the output setting, SPD-3606 operates
in Constant Voltage mode. The
indicator on the front panel turns green
(C.V.) The Voltage level is kept at the
setting and the Current level fluctuates
according to the load condition until it
reaches the output current setting.
When the current level reaches the output setting, SPD-3606 starts
operating in Constant Current mode.
The indicator on the front panel turns
red (C.C.) The Current level is kept at
the setting but the Voltage level
becomes lower than the settin
to suppress the output power level
from overload. When the current level
becomes lower than the setting, SPD3606 goes back to the Constant Voltage
mode.

Q1. I cannot turn On the output (the Output key does not respond).
A1. The following scenarios are possible.
• The rear panel remote control terminal is in the Off position. In
this case, set it to the On position or deactivate remote control. For
details, see page39.
• The OVP setting switch on the rear panel is on the SET side. In
this case, set the switch to the Normal side.
• The OVP indicator is red. In this case, change the OVP setting to
higher value or remove the over voltage condition.
Note that in several conditions, the Output key automatically turns
Off to avoid harmful condition. For details, see page25.
Q2. The CV/CC indicator is red (Constant Current) while the output is Off.
A2. This indicates there is an internal error. Contact the service
center.
Q3. The meter does not match the real value.
A3. The following scenarios are possible.
• Make sure the rear panel OVP setting is in the “Normal” position.
If the OVP switch is in the “SET” position, the meter might show
the OVP setting, not the output value. For OVP details, see page22.
• If you are using Channel1 or Channel3, make sure the meter
switch on the right side is in the correct position. Channel1 and 3
share the same meter.
