ALUMINIUM HOUSED POWER RESISTOR TYPE CFH SERIES INTRODUCTION The CFH series is a high quality range of aluminium housed power resistors offering environmental protection to IP65 and 66, elevated dielectric strength, and high impulse withstand capabilities. The nominal power of the CFH resistors is particularly high. This is obtained with a compact and insulated construction without accessible live parts, and using special inorganic materials that are capable of resisting temperatures above 400°C without damage. Moreover, the rated power of these resistors may be improved using a suitable additional heat sink. FEATURES • Up to 1.35kW in free air • Environmental protection to IP65 as standard • High pulse capability • Slimline casing • RoHS and REACH compliant APPLICATIONS • Dynamic braking • Capacitor charge/discharge • Traction general employment • Inverter • Snubber CHARACTERISTICS – ELECTRICAL Characteristic CFH350 CFH500 CFH750 CFH1100 CFH1200 Power rating (PR) (W) 330 410 700 1000 1350 Max. surface temperature @PR (°C) 310 320 330 335 390 0.5 ~ 15K 40 ~ 300 Pulse load @40°C, duty 5 sec, cycle 120 sec Up to 7.5 x PR Pulse load @40°C, duty 10 sec, cycle 120 sec Up to 5 x PR Pulse load @40°C, duty 20 sec, cycle 120 sec Up to 2.8 x PR Pulse load @40°C, duty 40 sec, cycle 120 sec Up to 1.7 x PR Resistance range (Ω) Resistance tolerance Voltage limit Dielectric strength @50Hz x 60sec 0.5 ~ 7.5K 0.5 ~ 10K 0.5 ~ 12K ±5% √(P*R) OR 1500V whichever is smaller 4500 Vrms Aluminium Housed Power Resistor Type CFH Series Characteristic CFH350 CFH500 CFH750 Insulation resistance in dry condition @1000 Vdc x 60 sec CFH1100 CFH1200 >250MΩ Time constant ~ 6.54 min ~ 6.22 min ~ 5.95 min ~ 6.19 min ~ 6.71 min ~ 30 min ~ 36 min ~ 36 min ~ 27 min ~ 30 min Thermal capacity (J/K) ~ 405 ~ 528 ~ 757 ~ 1109 ~ 1469 Thermal resistance @20°C (K/W) ~0.97 ~ 0.71 ~ 0.47 ~ 0.34 ~ 0.27 Specific power (W/cm²) ~ 0.61 ~ 0.53 ~ 0.67 ~ 0.66 ~ 0.68 102000 132000 189200 278000 368000 Time to reach the steady state Absorbed energy @250 KΔT (J) Operating temperature range -55 ~ 70°C Storage temperature range -55 ~ 90°C DIMENSIONS (UNIT: mm) Standard Special CFH350 CFH500 CFH750 CFH1100 CFH1200 L±2 (mm) 110 160 220 320 420 P±1.5 (mm) 60 110 140 240 340 Cable type standard High temp 2,5 mm² – Spark test voltage 4,5 kV (for ≤5 Ω 4,0 mm²) Cable type optional UL AWG 12 – Spark test voltage 6 kV (for ≤5 Ω AWG 11) Weight (kg) INDUSTRIAL / CFH SERIES 0.460 0.600 0.8600 1.260 1.670 2 Aluminium Housed Power Resistor Type CFH Series TWO VERSIONS Version Ingress protection Standard (CFH) Special (CFH/S) IP 65 IP 66 Special features Screwed front and rear metallic panels with nickel plated brass PG7 cable glands* *The special models CFH 350-500-750-1100-1200 have a slightly modified housing for the addition of two longitudinal bulges on the side surfaces to allow the housing of the tightening screws for fixing the metal heads to increase the degree of protection for special uses (IP66, railway sector, cable glands, etc. only if requested by Customer).

RATED VOLTAGE The maximum working voltage (√(P*R)) must always be lower than the maximum limit voltage (1500v), consistent with the insulation class of 4.5kV. Therefore, the applicable power must always be evaluated on the basis of the Ohmic value and the limit voltage. High Ohmic values and powers (in the feasibility ranges) can make the working voltage exceed the limit voltage or even exceed the insulation class of the product. ENERGY LEVEL The energy level depends on the ohmic value, average power, and application time (the values shown refer to average ohmic values). The energy level and rated power are maximized in the resistor with low to medium Ohmic values, whereas for high Ohmic values, the energy level and rated power must be reduced proportionally. INDUSTRIAL / CFH SERIES 3 Aluminium Housed Power Resistor Type CFH Series OVERLOAD The resistors can withstand high overload during relative short time (on-time). During overload the active material reaches maximum temperature. During the rest period (off-time) the energy is further released into the air. The cycle time is the on-time plus the off-time and taken here as 120 seconds. Note: Continuous power rating (PR) was measured under laboratory conditions with resistor mounted in free air under optimal heat exchange conditions. The curve below shows the overload capability in multiples of the nominal power for pulse loads at given duration with a cycle time of 120 seconds.
