The high-power resistor series (HPR-300) with a maximum power dissipation of 300 watts (with heat sink) is ideal for testing amplifiers and power amplifiers under full load. A simple series connection allows a multiple of 300 watts to be realized if higher power is required. But this high-load resistor is also the first choice in crossover design when it comes to matching powerful systems or loudspeakers. Maximum power dissipation with heat sink: 300 W Maximum power dissipation without heat sink: 75 W Dimensions: 172 x 72 x 40 mm R tolerance: ± 5 %
