You are over complicating it.
Use what I wrote originally as your template and rather than adding html and trying to make angular js evaluate it. $sce is for outputting html, not another directive. I should have looked more closely at what you are doing....
increment a counter then make it ng-repeat n times depending on how big your number value is.
 app.component("pointCom", {
    bindings: {
          point: "<",
          qty: "@",
          min: "@",
          max: "@"
        },
        controller: dataController,
        controllerAs: "dc",
        template:`
        <span>Render</span>
       <div ng-repeat="idx in dc.sour track by $index">
        <ma-get-point-value point-xid="DP_{{idx}}_Meter_kWh" point="dc.pts['c'+idx+'_Meter_kWh']"></ma-get-point-value>
        <ma-get-point-value point-xid="DP_{{idx}}_Meter_V" point="dc.pts['c'+idx+'_Meter_V']"></ma-get-point-value>
        <ma-get-point-value point-xid="DP_{{idx}}_Meter_A" point="dc.pts['c'+idx+'_Meter_A']"></ma-get-point-value>  
</div> 
`
      });
      
      dataController.$inject = ["$scope"]
      
      function dataController($scope){
          let dc = this
          let P = dc.point
          let Q = dc.qty
          let min = dc.min
          let max = dc.max
          let num = 0
          
          this.$onChanges = function() {
              let p = dc.point
              dc.sour = []
              max = dc.max
              num = dc.min
              console.log(school)
              if (max !== undefined){
                  Q = max
              } else {
                  Q = dc.qty
              }
              if (p !== undefined){
                  for (let i=0; i < Q; i++){
                  num = Number(num)
                  num = num.pad(3)
                  dc.sour.push(num)
                }
                console.log(dc.sour)
                
              }
            }
            
            Number.prototype.pad = function(size) {
            	let s = String(this)
            	while (s.length < (size || 2)) {s = "0" + s;}
            	return s
            }
            
        }
Try that and see how you go. Haven't tested this
