118073-001 Rev C 

4.4 Control Circuits 

Control circuits are used for regulation, monitoring, 
pulse-width, control, slow-start and inhibit control. 

 

Feedback signals are calibrated and buffered via general 
purpose OP-AMPS.  Pulse width control is accomplished 
by a typical PWM type control I.C.  Logic enable/disable 
is provided by a logic gate I.C.  Regulators generate ± 
15Vdc and 10Vdc. DSP based control circuitry provides 
excellent regulation, along with outstanding stability 
performance 

WARNING 

LINE VOLTAGE IS PRESENT 

WHENEVER THE POWER SUPPLY IS 

CONNECTED TO EXTERNAL LINE 

VOLTAGES.  BE SURE TO DISCONNECT 

THE LINE CORD BEFORE OPENING THE 

UNIT.  ALLOW 5 MINUTES FOR 

INTERNAL CAPACITANCE TO 

DISCHARGE BEFORE REMOVING ANY 

COVER. 

 

4.5 Options         

Due to the variations of models and options provided in 
the SLM series, details of actual circuits used may differ 
slightly from above descriptions.  Consult Spellman’s 
Engineering Department for questions regarding the 
principles of operations for the SLM series.
