Rackmount and Standalone Models:

SLH Family

Fully programmable, high power AC or DC electronic loads. The 500V models are for PFC testing, power transformers and various other AC or DC power sources. The 300V models are used for testing of UPSs, automatic voltage regulators (AVR), and batteries.

• High current, 60V DC models for general purpose power supply testing

• High voltage, AC/DC models intended for inverter test, Power Factor Correction (PFC) circuit testing (500V) and UPS testing (300V)

Modular Models:

SLM Chassis

The SLM chassis are available in a convenient single-bay configuration (see image on the right) for benchtop/desktop applications and a four-bay configuration (see image on the left) for multichannel and ATE requirements. Either chassis is compatible with SLM- and SLD- loads. Each chassis contains non-volatile memory capable of storing up to 150 module setups and nine 16-step sequences for automated, standalone testing. Or for more complex test sequences, the chassis come with GPIB (optional on SLM-1) and RS-232 as standard interfaces.

SLM Family

The SLM family includes 11 models of fully programmable, single input AC or DC modular electronic loads. DC models are offered to test power supplies, battery chargers, battery discharge, power supply transient response and integration into ATE systems. AC models are ideal to test low power inverters.

The DC models support operation in Constant Current, Constant Voltage, Constant Resistance or Constant Power mode as well as a short simulation. Engineers have ultimate control of current waveforms by using either the analog input or CC dynamic mode. An analog input (single input DC models) allows arbitrary current waveforms up to 20kHz with an external 0-10V signal. In dynamic mode, the pulse generator allows fast state switching between two programmed current levels with programmed slew rate and dwell times.

SLD Family

The SLD family offers six models of fully programmable, dual input modular electronic loads.

These DC modules are specifically designed for low power, high channel count testing and provide the highest channel density available.

(The double wide, dual channel module is seen here, but the single wide, dual channel model is not pictured.)
