Electronic loads offer high current capability
The Dynaload RBL Series of single-channel electronic loads offer an exceptionally high current rating of 1000A, and are ideal for the testing of large batteries and other DC power equipment.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Compliance will be a mandatory part of CE marking.
The HA1600 mains and harmonics analyser is supplemented by the AC1000 low-distortion AC power supply to provide a complete solution for rapid and precise measurements conforming fully with the standard.
The HA1600 has a 16 A current capability, and uses a shunt resistance of 3 mW as defined by the standard.
The large backlit LCD display provides both graphical and numeric displays.
The instrument has RS-232 and parallel printer interfaces built in, as well as isolated monitor outputs which provide re-constructed voltage and current signals.
The new unit provides numerical and graphical analysis of mains harmonics from the first to the 40th to very high accuracy.
Harmonics can be displayed as lists or as histograms with the compliance limits automatically calculated and displayed.
Simple pass/fail analysis can be done, or detailed failure information can be rapidly extracted.
The fast update rate allows real-time monitoring of circuit changes.
The HA1600 is capable of continuous real-time analysis of both voltage and current.
As a general-purpose mains analyser, it can measure watts, voltamperes, RMS and peak voltage and current, crest factors, total harmonic distortion, power factor, frequency and inrush current with a rating of 16 A RMS continuous.
The AC1000 is a 1 kW power source which removes distortions from the AC mains waveform to provide a pure sinusoidal source as required by the standard.
It is rated at up to 1000 VA for 230 V operation, and has a continuous current rating of 4.4 A and a peak current rating of 10 A.
In contrast to products which use a passive filtering approach, it uses an innovative technique which actively corrects the AC supply to produce a harmonically pure output.
The two TTi units can be supplied with a variety of mains connectors to suit different national standards.
The HA1600 and AC1000 package costs ?1490 (plus VAT) in the UK.
