AC OROC CONTAOL _ 35! GK +e SS BULLETIN 801C CRYVJOM COMPAN Y SERIES 1 SCR Output Solid-State Relays 2.5 Thru 90 Amp 24-480 VAC Output A General Description Crydom's Series 1 premium line, solid-state power relays incorporate inverse-parallel SCR output devices in the original standard Crydom package with the same highly reliable, noise-immune drive circuitry that has been a Cry- dom feature for more than a decade. Snubbers are included for high dv/dt applications and inductive loads, with a choice of models offering zero-voltage switching to reduce high inrush currents and electrical noise or Phase Controllable modeis for random turn-on. The oversized output chips, together with the Crydom optimized thermal management system, allows a narrower band of temperature excursions, resulting in a significant reduction in thermal cycling fatigue, thereby extending relay life. These premium devices are recommended for use in high temperature, highly inductive load situations where the ultimate in thermal and surge performance is required. Zero Voltage Models The inherent zero-current turn-off characteristic of SCRs, and the total absence of arcing mechanical contacts, sub- stantially reduces electro-magnetic interference and back EMF transients. AC input models can be controlled froma wide range of AC Signal Sources (90-280 VAC), and are available in Form A (normally open) configuration only. DC input versions will operate from IC logic signals, and are available in either Form A (SPST-normaily open) or Form B (SPST, normally closed) output configurations. Phase Controllable Models The -10 versions of DC Input Series 1 Relays are non-zero voltage (random) turn-on types, and are optimized for operation from a phase-controlled signal applied at each half of the line cycle. They nave been designed for phase control of incandescent lamps or any load with a power factor between 0.6 and 1.0.

When used for phase control, inductive loads may give rise to ringing and voltage overshoot that could exceed the relays peak transient rating. If this occurs, consideration might be given to the use of a metal oxide varistor (MOV) transient suppressor to protect the relay. In addition to the pulse width requirement, the pulse termi- nation (Tp) and initiation (Tp) parameters must be satis- fied. The zero current time (To) is defined as that time when the current through the relays output terminals passes through Zera.

It is essential that the user provide ade- quate heat sinking for the application. The simplified thermal model (Figure 1) indicates the basic elements to be considered in the thermal design. The values to be chosen or determined by the user are the case-to-heatsink interface thermal resistance (Rycs) and the heatsink-to-ambient thermal resistance (Ry,sa). Referring to Figures 4 thru 9, the left haives show power dissipation versus load current. The right halves are fami- lies of curves which are used in selecting the required heatsink to maintain a maximum case temperature for a given ambient. It is important to note that the thermal re-~ sistance values (C/W) shown include both case-to-heat- sink interface (R,-5) as well as the heatsink-to-ambient thermal resistance (R,,,). Thus, when selecting a heatsink, the value of (Rycs) Must be subtracted from the number indicated by the curve in order to determine the (Rys,). AS a point of information, if the SSR is firmly mounted ona smooth heatsink surface using thermally conductive grease, the vaiue of Ric, (case-to-heatsink interface) will typically be 0.1 C/W ar less. Examples of how the curves are used are explained below in conjunction with Figure 3. Example 1 If a 01225 is mounted on a heatsink with a thermal resis- tance of 1C/W (including R,5) and must operate in an ambient of 60C, the allowable current of 23A may be determined by following the route A,B,C,D (Figure 3). Additional information on power dissipation and maximum allowable case temperature can be found by extending line C,8 to points E and F where the values of 26W and 89C are read. Example 2 If acurrent of 17A is required for a 01225 in an ambient of 55C", the necessary heatsink, plus interface, thermal re- No Heatsink Ow- ) w) Resc Reca Output Semi- 4 @ > Heat Flow Ambient conductor . . {Air (Junction With Heatsink Temp Temp- )-- ~w- (7) ww (7) erature) erature) Resc + Recs + Resa Heatsink Case Temperature Temperature Te -T,z= Py (Reca) THERMAL RESISTANCE: = Fo (Recs + Rosa) Reuc = Junction to Case here Py = Power Reca = Case to Ambient Dissipation (Watts) Recs = Case to Sink Rega = Sink to Ambient Figure 1. Simplified Thermal Model sistance of 2.7C/W may be determined by following the route IJ.K,L (Figure 3). Additional information on power dissipation and case temperature can be found by extend- ing line J,L to points M and N where the values of 16W and 99C are read. This information can be used in heatsink selection from manufacturer's dissipation versus thermal resistance curves such as those shown in Figure 2. The thermal re- sistance of curve (a) at 16 watts is 2.5 C/W. This is better than the required 2.7 C/W in example 2, allowing 0.2 C/W for Rycg, and is therefore suitable for this application. Alternatively, heatsink (b) at 16 watts is 1.9C/W. Adding 0.1 C/W for R,5 and returning to Figure 3, 1t would allow operation at d maximum ambient of 65 C instead of 55C. Confirmation of proper heatsink selection can be achieved by actual temperature measurement under worst case conditions. The measurement can be taken on the metal baseplate in the area of the mounting screw, and should not exceed the maximum allowable case temperature shown in graphs. 35 25 20 THERMAL RESISTANCE IRgsa C/W) POWER DISSIPATION (W) ORSSIPATION (Waits!
