PLZ4W data sheet - .PDF file.

Telonic Instruments has introduced the PLZ4W range of electronic loads, which, claimed to feature faster rise and fall times with variable slew rates, is designed for transient testing on high-speed DC/DC converters and DC power supplies.

The PLZ4W’s test modes are constant resistance, constant current, constant power, constant voltage, or a combination of these modes.

It has a number of useful functions, including sequence function — which permits 10 sequence patterns to be saved in the built-in memory.

Telonic Instruments

Telonic Instruments supplies a wide range of programmable power supplies, both AC and DC, a range of electrical safety testers, DC electronic loads, general-purpose test equipment including bench multimeters, and a range of RF filters and attenuators.

The AC power supplies are of linear amplifier and pwm design with outputs up to 40kVA depending on model. In addition to variable frequency, variable voltage outputs some of  the AC power supplies can simulate AC supply line faults and have a large number of measurement functions including current harmonics.

The laboratory DC supplies sold by Telonic have power outputs to 1MW with voltages up to 4,000V, and includes linear and switch mode designs. Telonic also supplies electronic loads for power supply testing. These can operate in static or dynamic modes and can simulate rapidly changing current demands on power supplies.

To complement the line-up of AC and DC power supplies even further, programmable DC and AC electronic loads are also available. They have a voltage range from 0–650V and power capability of up to 9kW. They are commonly used for power supply, battery, fuel cell and inverter testing.

Electrical safety testers are another Telonic speciality. Concentrating mainly on production test applications Telonic supplies AC and DC flash testers, insulation testers, leakage current testers and earth bond testers. Manual and programmable versions are available.

Telonic can also supply a range of RF filters and attenuators. The RF filter range encompasses custom-built fixed low pass and bandpass types and also tuneable bandpass and notch filters. Frequency range is up to 12GHz for fixed filters and 4GHz for tunables.

Telonic is an ISO9001-registered company and has been supplying electronics industry, research establishments and universities since 1968.

Many of the products in the Telonic range are also available for hire.
