Page 3: Introduction
INTRODUCTION • The 123D variable speed control is available in a range of 150mA through 5.5 ADC (or up to 10 ADC if using a suitable external heatsink) at 24 through 36 VAC input. • The 125D variable speed control is available in a range of 150mA through 1/4 H.P. at 120/240 VAC input. -
Page 4: Mounting Procedure
---------- 15 AMP NOTE: To determine fusing for the 123D-C Series control (24 to 36 VAC input), use 200% of Full Load Current. TERMINAL STRIP WIRING INSTRUCTIONS The 125D Series uses an 8 position terminal strip for ease of connection. -

NOTE: ADDITIONAL CUSTOMER HEATSINK REQUIRED FOR 125DV-C (120 VAC INPUT - GREATER THAN 1/2 H.P. MOTORS) AND (240 VAC INPUT - GREATER THAN 1 H.P. MOTORS). 125 EXTRUSION TEMPERATURES SHOULD NOT EXCEED 70 DEGREES C. NOTE: FOR DETERMINING TRIMPOT SETTINGS FOR THE 123D-C SERIES, SEE TRIMPOT SETTINGS PROCEDURE BELOW. TRIMPOT... -

CONTROL MODIFICATIONS TWO SPEED OPERATION DYNAMIC BRAKING Two pot operation is done using two 10K A DPDT switch is used to inhibit the control and to connect the ohm speed potentiometers in parallel (both DBR. Typical values for the DBR (dynamic brake resistor) are 5 HI's to P1-6, both LO's to P1-8). -
