WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with
the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the
colours marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the
Earth terminal marked with the letter E or by the earth symbol
or
coloured Green or Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or
contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, cable of
0.75mm
2
should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection
method used.
Any moulded mains connector that requires removal /replacement
must be destroyed by removal of any fuse & fuse carrier and disposed
of immediately, as a plug with bared wires is hazardous if a engaged in
live socket. Any re-wiring must be carried out in accordance with the
information detailed on this label.

PCB A
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

from each channel. Internal components are placed
on four printed circuit boards, A ~ D.

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 Rect
ifier 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.

Controller
The C
ontroller 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
ailed description of each unit follows.
Det
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.

CV/CC Crossover Characteristics
Background
Diagram
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 curre
nt 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.
