236 Series - Adjustable Voltage Sensor SPDT, DPDT, 10-13 Amp The 236 series voltage sensor combines solid state sensing circuitry with a SPDT 13 amp relay or a DPDT 10 amp relay. The single pole version has recessed potentiometers for adjustment. The double pole version has knob adjustments. Pull-in voltage is 75 to 115% of nominal voltage. Dropout is 75 to 95% of set pick up. Applications: Brownout protection, warning of under voltage condidtions and over voltage protection. **Prevents equipment burn out** GENERAL SPECIFICATIONS (@ 25 C) Contacts: Contact Configuration Contact Material Contact Rating 120 / 240VAC Resistive 28VDC Resistive Motor 120VAC Motor 240VAC Minimum Contct Load Contact Resistance, Initial SPDT, DPDT Silver Alloy SP =13 Amp / 13 Amp, DP = 10 Amp / 10 Amp SP = 13 Amp, DP = 10 Amp 1/3Hp 1/2Hp 500mW 100 milliohms max @ 6VDC Coil: Coils Available AC and DC Power Consumption 3.5VA, 3.5W Input Voltage Absolute Maximum Lowest of +60% of nominal or 600VAC Pickup Voltage Range 75% to 115% of nominal Dropout Voltage Range 75% to 95% of set pickup Transient Protection Yes Reverse Polarity Protection Yes Duty Continuous Temperature: Operating Storage -20 to 55C (-4 to 131F) -40 to 85C (-40 to 185F) Life Expectancy: Electrical (full load operations) Mechanical (no load operations) Miscellaneous: Mounting Position Mating Socket Accessories Enclosure Weight 500Vrms 1500Vrms 1,000 Mohms min @ 500VDC 1 2 3 4 5 6 7 8 9 A B 100,000 SPDT = 5,000,000 DPDT = 10,000,000 Input Square Base Any SPDT = SK-SQB11-DS DPDT = SK-CIR8-DS Opaque Polycarbonate SPDT = 4.4oz (125 grams) DPDT = 5.5oz (156 grams) 4 5 3 6 2 7 1 8 Dielectric Strength: Across Open Contacts Between Mutally Insulated Points Insulation Resistance 236 Wire Diagram Input Octal Base 7/25 www.struthers-dunn.com (843) 346-4427 Timer / Sensor - Voltage Sensing Relay 10 - 13 Amp Outline Dimensions Dimensions Shown in inches & (millimeters) Octal Base Square Base 1.47 (37.5) Screwdriver adjustable 0.56 (14.2) 1.35 (34.2) LED Dropout Pull-in 2.62 (66.6) 2.88 (73.0) 0.80 (20.3) 2 9 4 1.40 (35.4) 1 2 3 4 5 6 2.44 (62.0) Section 7 8 6 7 3 5 1.77 (44.9) 0.19 (4.9) 1.53 (38.9) 236 Part Number Chart Part number Nominal input voltage Octal Base 236ACPX-1 120VAC 236ACPX-4 24VAC 236CPX-1 24VDC Square Base 236ACX-1 120VAC 236ACX-2 208/240VAC 236ACX-1 480VAC www.struthers-dunn.com (843) 346-4427 7/26
